2.1 Service Condition
1) Ambient Temperature: MAX 40 / MIN -25°
2) Relative Humidity: Less than 95%
3) Site Altitude: Less than 1000 m
2.2 Motor Drive
HVF & HAF VCB have motor-spring type stored-energy
operating mechanism. The closing operation can be done
only after the closing spring is charged.
Consumption during the operation is shown in Table 2-2,
and the inrush current may be disregarded since it lasts for
only a brief period.
The closing spring is fully tensioned by motor (M1) with the
rated voltage applied through terminal no.1&2 of standard
control circuit. Then the limit switch (S21, S22) stop the
motor, and the spring indicator shows "SPRING CHARGED"
by link activation as shown in Fig. 2-1. The charged VCB
can carry out the open-close-open sequential operation
and also the next close-open operation without delay.
Consideration of site altitude!!!
If the site altitude is higher than 1000 m, dielectric
strength of the breaker will be reduced according to
the altitude. Therefore, the values of power frequency
withstand voltage and lightning impulse withstand
voltage should be selected as following.
Rated withstand voltage according to rated voltage
X k(k: Refer to Table 2-1.)
For higher humidity, it is required to use a heater in the
switchgear to prevent dewdrops on the insulation
material and the consecutive decrease in dielectric strength.

2.3 Multiple Auto-Reclosing
HVF & HAF circuit breakers are capable of auto-reclosing
and can also be used for multiple reclosing for the
following operating sequence
O-0.3s-CO-15s-CO-15s-CO..... (O: tripping; C: closing)
2.4 Interlock Mechanism of the Draw-Out Type Breaker
The draw-out type circuit breaker has an interlock
mechanism which prevents trouble due to misoperation.
The sensing parts check the position of the circuit breaker
and prevent it from closing if the associated disconnector is
not allowed for safe operation.
2.5 Closing (Y9) and Anti-Pumping (K1)
When closing authorization is applied through terminals no.
6 & 7, Solenoid Y9 unlatches the closing spring, and thus
closes the circuit breaker electrically. Immediately after the
breaker closes, Aux. S/W, S1 the closing circuit, and limit
switch S3 and anti-pumping relay K1 switch affect to Y9 so
that they can not be reactivated until the continuous
closing command is interrupted.
Thus the breaker can meet the IEC requirements for anti-
pumping and trip-free opeation. At the same time, the
contact pressure spring is compressed properly to maintain
sufficient contact pressure on the moving contact of the
vacuum interrupters while the breaker is in the closed
position, and the tripping spring is compressed for the
opening operation.
2.6 Open Solenoid (Y1)
When the opening command is applied, the tripping spring
is unlatched by the trip solenoid Y1 and the force turns the
torque to rotate the brake shaft to make the opening
position. Immediately after the breaker is open, the
indicator displays the open state and Aux. S/W, S1 open
the opening circuit.
2.7 Auxiliary Switch (S1)
The standard auxiliary contacts for external connection are
composed of 4NO+4NC. These contacts are wired to the
control jack (XO).
Rated Insulation Voltage: AC/DC 250 V
Continuous Current: 10 A
Making Current: 30 A
Switching Current: 2 A at DC 220 V, =20 ms
The maximum connection 10NO+10NC is available on request.

Misoperation or carelessness may result in
serious injury or property damage.
With the breaker closed, the draw in & out operation is
impossible. Do not push too hard on the breaker under
improper condition.
오조작, 또는 부주의가 중상 혹은 재산 피해를 일으킬 수 있습니다.

2.8 Condenser Trip Device
It is recommended to employ the capacitor trip unit for a
trip operation of the breaker when the control source is
lost in the AC control system.
If contacts B1, B2(1.5sec delay contact) of auxiliary relay
are connected with tripping push button as shown below,
the breaker can be opened automatically in case of power
failure and terminals 5, 7 can be used as AC power supply
connecting to the motor or closing circuit.

which can trip the breaker just one time.
It cannot be operated properly if used for other
purposes or if the circuit is modufued without
consulting the manufacturer.

2.9 Under Voltage Release (Y7)
The UVR (Y7) having a spring-energy storing mechanism, is
used for the continous monitoring of circuits, and can open
the circuit breaker automatically when the control voltage
drops lower than the drop-out voltage.
And the latching mechanism of the release can be excited
to hold the cloisng condition of the circuit breaker when
the control voltage rise than the pick-up voltage.
Drop-out voltage: 35~60% of rated control voltage
Pick-up voltage: 75~85% of rated control voltage
If it is necceary to lock the automatical tripping function of
the release at the lower control voltage, you can place the
lock-screw as shown in Fig. 2-6.
And the release can be operated again by shifting the
screw down as shown in Fig. 2-7.
2.10 2nd Open Solenoid (Y2)
2nd trip solenoid (Y2) can be attached to the HYUNDAI
HAF/HVF circuit breaker putting aside the 1st trip solenoid
(Y1), so that the circuit breaker can be opened with more
safety.
2.11 Cutout Switch
The cutout switch consists of two limit switches, which are
connected in series with the impulse contact of the
auxiliary switch in the alarm circuit.
When the VCB is opened locally, the cutout switch
interrupts the tripping signal.
Closing time of impulse contact is more than 10ms.
2.12 “Closing Spring Charge” Signal
Using the auxiliary switches S41, S42 operated by the
closing spring, the spring charged indicator is displayed for
visual checking.

3.1 Unloading and Storage
When unloading from the vehicle, avoid turning if over.
Special care should be taken to avoid shocks.
If vacuum circuit breakers must be stored prior to use, they
should be stored only in dry, dust-free and well ventilated
rooms, with the breakers in the OFF position and the
stored-energy spring mechanism in the released position.
3.2 Unpacking
When opening the package, also avoid turning it over and
special care should be taken to not damage the breaker.
Handle carefully disconnecting unit, front panel and so on.
3.3 Inspection After Unpacking
1) Check the type rating and quantities with the
specification sheet.
2) Check the circuit breaker for any damage or missing
materials.
3) Check all accessories and spares supplied. Also, check
to see if these parts are damaged.
3.4 Installation
Before installing the circuit breaker into the switchgear,
check the type rating and for any signs of damage again.
Wipe the breaker with a dry cloth to remove dirt and dust.
Mount the draw-out unit (if it is used) on a level floor by
means of screwing through the mounting holes on the
bottom. Then, the tolerance on the level should be within
1 mm. If required. adjust the level using a liner.

4.3 Operation Mode
1) Charging
When the charging mechanism
is activated by hand or motor
(31), the charging shaft (11-1)
turns by the gears and the
driver (11-2) so that the closing
spring (12) is tensioned. When
the closing spring is fully
tensioned, the closing pawl
(11-3) makes the closing spring
be latched.
2) Closing
When closing command is
applied, the closing spring is
unlatched by the activation of
the closing pawl. Through the
energy from the discharging of
the closing spring, the coupling
bar is powerfully pushed down
via the charging shaft and the
cam.
Consequently, the breaker shaft
is turned until the moving
contact is fully closed and
latched by the trip pawl (25-1).
At the same time, the contact
pressure spring (49) is
compressed to insure sufficient
contact pressure on the moving
contact while the breaker is in
the closed position, and the
tripping spring (13) is
compressed for the opening
operation.
3) Recharging
After the closing operation, the
closing spring can be
immediately recharged bya
motor (31) or hand so that the
breaker immediately re-closes
in case the closing authorization
re-closes is applied.
4) Opening
When opening command is
applied, the tripping spring is
unlatched by the activation of
the trip pawl, and the breaker
shaft is returned to the open
position.

Before inserting or withdrawing, the breaker should be
open. Before turning the handle, lift up the Interlock
Handle. If excessive power is applied to the handle
when the breaker is closed or the Interlock Handle is
not lifted up, it can cause damage to the breaker.
Make sure that the breaker and cradle have same
rating when inserting and withdrawing the breaker.
The sticker and name plate with rating are attached on
the product.

4.4 HAF VCB의 인출입 방법
1) Checking before inserting the breaker to
the switchgear or cradle Check first
whether the link is horizontal as shown in
Fig. 4-10. If not, put the handle into the
hole and turn it any direction to set the
link horizontal. After that, check to see if the
breaker is open.
