Terasaki’s TemPower2
A.C.B is the result of
an intensive market
research program
which took into ac-
count the require-
ments of switchboard
builders, consultants
and end users.
TemPower2 Air Circuit
Breaker is one of the
smallest in the market
with a 1 second rating
(Icw).
Innovations
New design built-in UVT that eliminates the need for the
controller to be mounted on the side of the ACB.
New Protection Relay range the AGR-B. The new AGR-B
range will have an improved LCD display, which will include
additional features such as an Ammeter, Zone Interlocking
and Multi/Power Meter capabilities. This will also mean
some changes to previous closing circuit configurations.

32
Increased accessibility from the front
It enhances ease of installation, operation, and maintenance.
No extra arc space required,
vertical stacking permitted
Replacement of
the main contacts
The fixed and moving main contacts can
easily be replaced in the field, thus prolong-
ing the life on the circuit breaker. Changing
each pole takes around 15 minutes.
The TemPower2 ACB dis-
sipates all arc energy within
its unique “DoubleBreak”
arc chamber. The internal
energy dissipation within the
ACB allows the clearance
distance of the ACB to
nearby earthed metal to be
zero. This will assist in mini-
mizing switchboard height
and costs.

TemPower2 is the world’s first
“Double Break” ACB, having two
breaking contacts per phase.
The unique pole structure
means that the short time
withstand rating (Icw, 1sec) is
equal to the service short-circuit
breaking capacity (Ics) for all
models. Full selectivity is
guaranteed up to the full system
fault level. TemPower2 ACBs
have the world’s smallest depth
resulting in space saving in
switchboards.
More than twenty design pat-
ents have been registered for
the TemPower2 ACB.
The height and depth dimensions are identical in all sizes up to 3200A. There are two common widths or
frame size, from 800-2000A and from 2500-3200A for the standard series. The panel cutout size is the same
for all types of TemPower2, which makes it easy to arrange the ACBs in switchboards.
Maximum power from minimum volume was central to the design specification. With a depth of 290mm for
the fixed type and 345mm for draw-out, it is one of the smallest ACBs in the world.
ACBs with front connections are available off-the-shelf.
Front connections are especially suitable for smaller-depth switchboards.
Icw,1s = Ics for all Tempower2 ACBs.

Draw-out operation
The double insulated design
ensures that most accesso-
ries can be safely and easily,
installed by the user. Control,
auxiliary and position switch
terminals are mounted at the
front on the ACB body for easy
access. Horizontal, vertical
and front terminal connec-
tions, can also be changed by
the user for any last minute
alterations. Due to the in-
creased level of harmonics
within the distribution network,
the neutral phase is fully rated
as standard.

54
No clamp screws used
for the main circuit
contact units
There are no clamp screws or flexible leads
in the main circuit contact units.
This substantially enhances the durability of
the main circuit contact units and improves
the reliability in ON-OFF operation.
Isolating main contact
Fixed main contact
Moving main contact
Main circuit contact units
Easy Maintenance
The unique design of TemPower2 incorporates its
isolating clusters and main contacts on the ACB body.
Allowing for quick easy maintenance of the main
electrical contact points and for maintenance to be
completed without having to isolate the switchboard.
Features
1
A high performance and reliability
Very fast interruption by
“DoubleBreak” system
The unique “DoubleBreak” main contact system
ensures extremely fast interruption of short circuit
currents and substantially reduces main contact wear.
The internally symmetrical “DoubleBreak” structure
means the moving contact is isolated from the supply
voltage even when the ACB is reverse connected.
The neutral pole of all TemPower2 ACBs are of early
make/late break design. This eliminates the risk of
abnormal line to neutral voltages, which may damage
sensitive electronic equipment.
“DoubleBreak” contacts increase service life -
Electrical and mechanical endurance ratings are the
best available, and exceed the requirements of IEC
60947-2.
Enhanced selectivity
At Terasaki our protection
relays have ‘LSI’ characteristics
as standard.
This provides an adjustable time
delay on overload (L) and also the
l2t ramp characteristic (S).
As shown, these are essential to
provide selectivity when grading
with other protective devices such
as downstream fuses and up-
stream relays.
The standard ‘LSI’ curve provides
more than five million combina-
tions of unique time current characteristics.
Zone selective interlocking is available to provide zero time delay selectivity.
As the rated breaking capacity is identical to the rated short-time withstand current full selectivity can be
achieved.

Contact temperature
monitoring function (optional)
This function monitors the temperature of the ACBs main con-
tacts. An alarm indicates when the temperature exceeds 155°C.
Continuous monitoring of the contact temperature provides
valuable input for preventative and predictive maintenance pro-
grams.
Two channel pre-trip alarm
function
(optional)
This function can be used to monitor and switch on additional
power backup to feed critical circuits. For example, the function
can be set so that when a pre-trip alarm is activated, an emer-
gency generator starts to ensure a constant supply. This fea-
ture is only available on some AGR22B/31B OCR models with
a generator “S” characteristic.
N-phase protection
function (optional)
In 3-phase, 4-wire systems that contain harmonic distortion,
the 3rd harmonic may cause large currents to flow through the
neutral conductor. The N-phase protection function prevents
the neutral conductor from sustaining damage or burnout due
to these large currents. Available in all OCRs except for gen-
erator “S” characteristic types.
Ground fault trip
function
This function eliminates external relays to provide a ground
fault protection to TN-C or TN-S power distribution systems on
the load side. Ground fault protection on the line side is also
available as an option.
Advanced L.C.D. display,
Over Current Relay
The AGR-31B OCR comes standard with an LCD display. It
can monitor and indicate phase currents, voltages, power, en-
ergy, power factor, frequency, and more. For features refer page

Overload protection
Adjustable from 40–100% of rated current. True r.m.s detec-
tion up to the 19th harmonic, a distant vision for the competi-
tion who rarely see past the 7th. Neutral protection for all those
Triple-N harmonics, such as 3rd, 9th and 15th. Also in case we
forgot to mention, a “thermal memory” ia available on the
AGR21B/31B.
Reverse power trip function
(S-characteristic)
This feature provides additional protection when paralleling
generators. The AGR22B/31B OCR for generator protection
with the reverse power trip function, negates the need for in-
stallation and wiring in an external reverse power relay. This
feature is available using an AGR OCR with a generator “S”
type characteristic only.
Earth leakage trip
function
Used in conjunction with an externally mounted Zero phase
Current Transformer (ZCT), this function provides protection
against leakage to earth of very small levels of current. Trip or
alarm indication, and contact output is available to enhance
the level of system protection.
Phase rotation
protection function
This function detects the negative-phase current occurring due
to reverse phase or phase loss and prevents burnout of a mo-
tor or damage to equipment.
External display
(optional)
If the ACB is installed in the switchboard so that overcurrent
release (OCR) indications are hidden to the operator, the use
of this large external display allows the operator to monitor the
indications. Out of phase currents, line voltages (or phase
voltages), power and power factor, up to 4 outputs can be read
as current signals (converted to 4 - 20 mA DC) on the external
display.

Optimum protective
coordination
Why use a separate panel mounted protection relay when
you can have all the benefits of I.D.M.T. protection integral to
the ACB?
TemPower2 is available with a choice of flexible protection curves
to assist in selectivity applications.
S.I. Standard Inverse
V.I. Very Inverse
E.I. Extremely Inverse
All these curves are user definable and comply with IEC 60255-3.
Standard transformer and generator protection characteristics are
also available.

I2t = S.I.
I3t = V.I.
I4t = E.I.
Inverse Definite Minimum Time (I.D.M.T.)
Zone Interlocking
In conventional discrimination systems, short time delays
are used to allow a short-circuit current to be tripped by
the circuit breaker nearest the fault. The disadvantage of
this type of system is during a fault; considerable thermal
and mechanical stresses are placed on the entire system.
With the TemPower2 Z Interlock system the breaker
nearest the fault irrespective of the short time delay
setting will trip first.
Example of operation:
If a fault occurs in Zone 2, only AR Z Interlock
‘A’ will sense any fault current fault, a no fault signal will
be sent by AR Z Interlock ‘B’ & ‘C’, consequently AR Z
Interlock ‘A’ trips the ACB immediately, overriding its short
time delay.
Protection relay
performance
Ensure that the ACB you specify suffers no loss of
performance when tripped by an external protection relay!
The TemPower2 ACB suffers no loss in performance when
tripped through an external protection relay.
Some competitor’s ACBs have reduced breaking
performance when an external protection relay is used.

Double opening and
closing coils
Double Opening and Closing Coils provides extended control
system redundancy to an ACB. Double coils allow designers to
implement back-up tripping and closing systems. It provides the
end user with ultimate reliability on critical UPS circuits
connected to critical loads.
Earthing Device
The unique design of TemPower2 ACBs allows for the
earthing of either the busbar (line) or the circuit (load) of a
low voltage system. Thus allowing system flexibility.
Some other manufactures only offer one option either,
busbar or circuit earthing.

Double Neutrals
System harmonics, in the face of increasing triple-N harmonic
currents Terasaki have launched a range of ACBs with double
neutrals from 800 – 6300Amps – The ‘AR-DN’. Terasaki have
the widest range of double rated neutral ACBs on the global
market.
TemCurve
TemCurve Selectivity Analysis Software is shaped
around the extensive range of Terasaki circuit break-
ers, but also includes a large number of complimen-
tary protective devices such as High and Low Voltage
Fuses to BS88/IEC269, IDMT Relays to BS142/
IEC255. As a result, TemCurve can assist in protection
device grading from the transformer primary to the
point of final distribution, giving the facility to produce
overcurrent and earth fault studies.

1Types of Mounting
Draw-out type
This type of ACB consists of a breaker body and a draw-out
cradle. The breaker body can be moved within or removed
from the draw-out cradle that is fixed in the switchboard.
There are four breaker body positions: CONNECTED, TEST,
ISOLATED, and WITHDRAWN. The switchboard panel door
can be kept closed in the CONNECTED, TEST, and ISOLATED
positions (“shut-in three positions”).
Fixed type (standard series only)
This type of ACB has no draw-out cradle and is designed to be
directly mounted in the switchboard.
Connection methods
Main circuit terminals
Three(3) types of main circuit terminal arrangements are avail-
able: vertical terminals, horizontal terminals, and front connec-
tions. Different types of terminal arrangements can be speci-
fied for the line and load sides. Unless otherwise specified by
the user, horizontal terminals are given to types AR208S,
AR212S and AR216S ACBs on both the line and load sides,
and vertical terminals to AR220S, AR235S, AR332S and AR
440S. For AR440S, only vertical terminals available. For High
fault series, vertical terminals are standard and horizontal ter-
minals are optional, and front connections are not available.

Position switches
The position switch operates to give an indication of the breaker position: CONNECTED, TEST, ISOLATED, and INSERT.
There are two contact arrangements: 2c and 4c.
Connections to the switches are made via screw type terminals.
The following table lists the available types of the switches.
Door interlock
The door interlock prevents the switchboard door from being opened unless the breaker body is in the ISOLATED position.
When the draw-out handle is removed while the ACB is in the ISOLATED position, the interlock is released and the switchboard
door can be opened.
The breaker body cannot be inserted unless the switchboard door is closed.
Contact Terasaki for details.
Note 1: When the door interlock is installed, the standard draw-out handle cannot be stored in the switchboard. A storage draw-
out handle is available as an option. The storage draw-out handle can be housed flush with the front surface of the
ACB. (The storage handle will incur extra cost).
Note 2: Contact TERASAKI for the details for fitting Door interlock with IP55 cover.

2Accessories for Draw-outType
Main circuit safety shutters
The main circuit safety shutters auto-
matically conceal the main circuit con-
tacts on the draw-out cradle when the
ACB is drawn out.
• The top and bottom shutters operate
independently and can be separately
padlocked in the closed position.
• Up to three padlocks (with ø6 hasp)
can be installed on each side using
padlocking unit. (Padlock not supplied)
• In the closed position, the shutters are
locked to the extent that they cannot
be easily unlocked by hand. They can
be unlocked and held open if required
for the purpose of inspection or main-
tenance.
Control circuit safety shutter
The control circuit safety shutter covers
the control circuit contacts, ensuring
safety.
Breaker fixing bolts
The breaker fixing bolts hold the breaker
body securely to the draw-out cradle in
position. Use them if the ACB is subject
to strong vibration.
Test jumper
The test jumper is a plug-in type, and
allows ON-OFF tests on all the
TemPower2 series ACBs with the
breaker body drawn out from the draw-
out cradle.
The standard jumper cable is 5 m long.
Position padlock lever
¶
Using the position padlock lever pre-
vents the breaker body from inadvert-
ently being drawn out. The position pad-
lock lever in the pulled-out position locks
the breaker body in the CONNECTED,
TEST, or ISOLATED position. Up to
three padlocks (with ø6 hasp) can be
installed.
Lifter
A special lifter is available to allow easy
and safe transportation or installation of
the ACB. A drop prevention mechanism
is standard.

Interchangeability exists within the
TemPower2 series of ACBs. Because
of this feature, there is a possibility for
an ACB of a different specification be-
ing placed into the draw-out cradle.
Using the mal-insertion prevention de-
vice eliminates such a possibility.
This device is capable of distinguishing
nine different breaker bodies.
Please specify the Code 1A, 1B, 1C, 2A,
2B, 2C, 3A, 3B, 3C for each ACB.

Motor charging type
For this type of ACB, the closing springs are charged by means of a motor. ON/OFF operation of the ACB can be performed
remotely.
A manual charging mechanism is also fitted to facilitate inspection or maintenance work.
Charging the closing springs
A motor is used to charge the closing springs.
When the closing springs are released to close the ACB, they are automatically charged again by the motor for the next ON
operation.
Closing the ACB
Turning on “remote” ON switch enables the ACB to be remotely closed.
• Anti-pumping mechanism
Even if the ON switch is kept on, ACB closing operation is performed only once.
To close the ACB again, remove the ON signal to reset the anti-pumping mechanism and then reapply the ON signal.
• If ON and OFF signals are simultaneously given to the ACB, the ON signal is ignored.
Opening the ACB
For opening the ACB remotely, specify the shunt trip device (See P. 23) or the undervoltage trip (See P. 24).
Step-down transformer (external)
The maximum rated control voltage applicable to
the operation power supply is AC240V. For higher
voltages, a step-down transformer is needed.
The following step-down transformers are available
as options.

Manual charging type
For this type of ACB, the closing springs are charged by means of the spring charging handle. ON/OFF operation of the ACB is
performed by means of ON/OFF buttons on the ACB.
Charging the closing springs
Pumping the spring charging handle by hand charges the closing springs.
Closing the ACB
Pressing the ON button on the ACB closes the ACB.
Opening the ACB
Pressing the OFF button on the ACB opens the ACB.
The ACB cannot be closed as long as the OFF button is pressed.

5Trip Devices
Capacitor trip device
In conjunction with the continuously-rated shunt trip device,
the capacitor trip device can be used to trip the ACB within a
limited period of 30 sec if a large voltage drop occurs due to an
ac power failure or short-circuit.
When the continuously-rated shunt trip is used with a capacitor
trip device, “a” contact of auxiliary switch of ACB should be
inserted in series, otherwise internal damage may occur.
Continuously-rated shunt trip device
The continuous-rated shunt trip device allows the ACB to be
opened when an external protection relay against overcurrent
or reverse power is activated.
Because of its continuous rating, the device can also be used
to provide an electrical interlock to the ACB.
Continuously rated shunt trip and undervoltage trip can not be
fitted to the same ACB. However, Instantaneously rated shunt
trip can be used together with undervoltage trip with special
specification. Special double opening and closing coils are
available, contact TERASAKI for details.

6Over-current Releases (OCRs)
The AGR series of over-current releases (OCRs) featuring high reliability and multiple protection capabilities is available for
TemPower2. Controlled by an internal 16-bit microprocessor, the OCR provides reliable protection against overcurrent.
The OCR range is divided into three groups: L-characteristic, R-characteristic (both for general feeder) and S-characteristic (for
generator protection).
Each group consists of:
Type AGR-11B: Standard OCR with adjustment dial
Type AGR-21B,22B: Standard OCR with L.C.D.
Type AGR-31B: Enhanced OCR with backlit L.C.D.
Optional protection functions of the OCR include those against ground fault, earth leakage, undervoltage and reverse power.
Pre-trip alarm function can also be installed.
Protective functions
qAdjustable long time-delay trip function LT
RMS sensing is used to accurately read through distorted wave-
forms.
In addition to the standard L and S-characteristics, the R-char-
acteristic is available in five types for long time-delay trip.
The R-characteristic can be used to give selectivity with e.g.
fuses. (See P. 8).
HOT start mode (applicable to L-characteristic of AGR-
21B,31B)
HOT or COLD start mode is user-selectable.
In HOT start mode, the OCR operates faster than in COLD
start mode in response to an overload. The HOT start mode
gives protection, taking account of the behavior of loads under
heat stress.
wAdjustable short time-delay trip function ST
The ST delay trip function has a “definite time delay character-
istic” and a “ramp characteristic”. These characteristics are
switch-selectable.
The ramp characteristic provides close selectivity with down-
stream circuit breakers or fuses.
The group AGR-L and AGR-R OCRs come in operation with
the definite time characteristic when the load current reaches
1000% or more of the rated current [
I
n] (500% or more of the
rated current [
I
n] for AGR-S).
The ST trip function is factory set to the definite time charac-
teristic.
eAdjustable instantaneous trip function INST/MCR
The INST trip function trips the ACB when the short circuit cur-
rent exceeds the pickup current setting, irrespective of the state
of the ACB.
The making current release (MCR) trips the ACB when the
short circuit current exceeds the pickup current setting during
closing operation. After the ACB is closed, the MCR is locked
and kept inoperative.
The INST and MCR are switch-selectable for AGR-21B, 22B
and 31B. (AGR-11B is INST only , MCR is not selectable)
Note) The MCR needs the control power. If the control power
is lost, the MCR provides the INST trip function only.

Undervoltage trip device (UVT)
The undervoltage trip device (UVT) trips the ACB when the
control voltage drops below the opening voltage. When the
control voltage is restored to the pick-up voltage, the ACB can
be closed. The pick-up voltage is fixed to 85% of the rated
voltage.
The UVT consists of a tripping mechanism and an undervoltage
trip control device. The trip control device is available in two
types: AUR-ICS and AUR-ICD.
Type AUR-ICS provides an instantaneous trip to the ACB when
the control voltage drops below the opening voltage.Type AUR-
ICD provides a delayed trip to the ACB when the control volt-
age remains below the opening voltage for at least 500 ms.
Adding a pushbutton switch (with normally opened contacts)
between terminals 24 and 30 allows the ACB to be tripped
remotely.
Undervoltage trip control circuit (for AC)
¶1 Tripping signal is 48 VDC/5 mA.
Apply tripping signal for at least 80 ms. If a constant
tripping signal is applied a n/o auxiliary switch must be
used in series with the PB.

NON setting and fail-safe feature
zNON setting
Setting a trip pickup current function to NON allows you to render
the corresponding protection function inoperative.
Functions having the NON option include LT, ST, INST/MCR,
and GF.
Appropriate NON setting will be a useful means for optimum
selectivity.
xFail-safe feature
The OCR has a fail-safe mechanism in case protection functions
are improperly set to NON.
• If the ST and INST trip pickup current functions are both set
to NON, the fail-safe mechanism will activate the INST trip
function to trip the ACB when a fault current equal to or more
than 16 times the rated current [
I
n] flows through the ACB.
• If the ST and MCR trip pickup current functions are both set
to NON, the fail safe mechanism will activate the ST delay
trip function to trip the ACB when a fault current equal to or
more than 10 times (5 times for generator protection) the rated
current [
I
n] flows through the ACB.
Specifications

rAdjustable pre-trip alarm function PTA
The pre-trip alarm function provides an alarm signal via the
alarm contact (1a-contact) when the load current exceeding a
predetermined value lasts for a predetermined time. A 2-chan-
nel pre-trip alarm function is available for S-characteristic. This
function can be used to adjust feeding to loads according to
their priority.
The pre-trip alarm is automatically reset when the load current
drops to the predetermined value.
Note that this function needs the control power.
tGround fault trip function GF
The peak value sensing is used (the residual current of each
phase is detected).
The GF pickup current can be set between 10% and 100% of
the CT rated primary current [
I
CT]. Not available if CT primary
current [
I
CT] is 200A or less.
<Ramp characteristic is added>
The ramp and definite time characteristics are switch select-
able. The GF trip function comes into operation with the defi-
nite time characteristic when the load current reaches 100%
or more of the CT rated primary current [
I
CT].
The GF trip function is factory set to the definite time charac-
teristic.
When using a 3-pole ACB in a 3-phase, 4-wire system, be
sure to use an optional CT for neutral line (see P. 39).
Note 1: The GF trip function comes usually with operation
indications. If you need nothing but ground fault
indication without a ground fault tripping operation,
specify at the time of ordering.
Note 2: Restricted and unrestricted ground fault protection REF
is available as option. This enables protection against
ground fault on the line side of the ACB.
yEarth leakage trip function ELT
(For AGR-31B only.)
In conjunction with an external Zero phase Current Transformer
(ZCT), the ELT function provides protection against earth leak-
age.
The ELT pickup current can be set at 0.2, 0.3, 0.5 and 1A
(Medium sensitivity) or 3 and 5A (Low sensitivity).
This function needs the control power.
Note 1: For details on specifications of the external ZCT,
contact Terasaki.
Note 2: The ELT function comes usually with operation
indications. If you need nothing but earth leakage
indications without earth leakage tripping
operation, specify at the time of ordering.
Note 3: The ELT function is available up to 2500A rated
current [
I
n]
uReverse power trip function RPT
(For AGR-22B and AGR-31B only.)
The RPT function protects 3-phase generators running in par-
allel against reverse power. The RPT pickup current can be
set in seven levels: 4% thru 10% of the generator rated power.
If the rated main circuit voltage exceeds 250 VAC, a step-down
power transformer is needed. When ordering the ACB, state
the step-down ratio of the transformer you will use.
iN-phase protection function NP
This NP function is available on 4-pole ACBs and prevents the
neutral conductor from suffering damage or burnout due to
overcurrent.
The NP trip pickup current can be set between 40% and 100%
of the OCR rated primary current for L and R-characteristics or
of the generator rated current for S-characteristic.
It is factory set to a value specified at the time of ordering.
Note 1: The NP trip function comes usually with operation
indications. The NP trip pickup current setting is shared
by the LT trip function.
Note 2: The HOT start mode is available for AGR-21B and
AGR-31B. The operating time for the NP trip function
is linked to that for the LT trip function.
Soon to be available
oContact temperature monitoring function OH
(For AGR-22B and AGR-31B only.)
The HEAT function prevents the ACB from suffering damage
due to overheat.
It monitors the temperature of the ACB main contacts, and
gives an alarm on the LCD and an output signal via the alarm
contact (1a-contact) when the temperature exceeds 155°C.
The alarm can be manually reset when the temperature drops
to a normal temperature.
If you want to set the threshold temperature to a lower value,
contact Terasaki.
This function needs the control power.
Note 1: "Alarm" or "Trip" can be selected.
!0 Phase rotation protection function NS
(For AGR-21B and AGR-31B only)
This function detects the negative-phase current occurring due
to reverse phase or phase loss and prevents burnout of a mo-
tor or damage to equipment. The protection setpoint ranges
from 20% to 100% of the main circuit rated current [
I
n].
!1Undervoltage alarm function UV
(For AGR-22B and AGR-31B only.)
This function monitors the main circuit voltage, and gives an
alarm on the LCD and an output signal via an alarm contact
when the voltage drops below the setting voltage.
The alarm is activated when the main circuit voltage drops
below the setting voltage (selectable from 40%, 60% or 80%
of the rated main circuit voltage [Vn]), and is deactivated when
the main circuit voltage rises to the recovery setting voltage
(selectable from 80%, 85%, 90% or 95% of the rated main
circuit voltage [Vn]).
If the rated main circuit voltage exceeds 250 VAC, a step-down
power transformer is needed. When ordering the ACB, state
the step-down ratio of the transformer you will use.
Note 1: The undervoltage alarm function is disabled unless
the main circuit voltage has once risen to the recovery
setting voltage or higher.
Note 2: If the undervoltage alarm function is used in conjunc-
tion with the undervoltage trip device (see page 24),
an alarm may occur after the ACB trips open depend-
ing on the alarm setting voltage.
!2Zone interlock Z
(For AGR-22B and AGR-31B only)
The zone-selective interlock capability permits tripping of the
ACB upstream of and nearest to a fault point in the shortest
operating time, irrespective of the short time delay trip time
setting, and minimizes thermal and mechanical damage to the
power distribution line.
Field test facility
Type AGR-21B/22B/31B OCRs are equipped with a field test function to verify the long time delay, short time delay, instantaneous
and ground fault trip features without the need for tripping of the ACB.
To check type AGR-11B, use the type ANU-1 OCR checker (optional).
