SECTION1: INTRODUCTION
1.1 GENERAL INFORMATION
TheTrip Unit Test Kit is used to test and verify the pickup
levels and time delay settings of a breaker’s Trip Unit. The
original Test Kits were developed to test the Amptector
Trip Units of the DS Breaker. With the introduction of
microprocessorbasedTrip Units(Digitrip,Optim, etc),
modificationstotheoriginalTestKits(-G01and–G02)
were required to accommodate lower power requirements
ofthemicroprocessor. These modifications,in combina-
tionwith variousTest Kit Adapters, allow maintenance
personnel to utilize theTest Kit they already own when
testing the newer generations ofTrip Units.
TheTest Kit Adapter (Style#8779C02G04) forthe Mag-
numDS DigitripTrip Units,convertsthe11-pin banana plug
on theTest Kit, to a 14-pin plug. This 14-pin plug, plugs
into the Trip Unit Test Port, located on the face of theTrip
Unit.(seeFigure4)
SECTION2: TESTKIT/ BREAKERINFORMATION
2.1 TEST KIT / ADAPTER INFORMATION
2.1.1 TESTKITCONTROLS(SEE FIGURE1)
The following are the identifications and fuctions of the
Test Kit controls. Any time these are referred to in the
following portions of this publicaiton they will be in italics
and underlined as shown in the following definitions of the
functions.
POWERON/OFF –Turns on powerto theTestKit.
STOP – This switch manually cuts offthe test current to
the Trip Unit.
LONGDELAYPICKUP -Thislightisnotfunctionalfor
MagnumDStrip units.
TEST – Starts the test.
RESET –ResetstheTest Kit afteratest.
CALIB –Usedinconjunctionwith CURRENTADJUST
allowing for setting a pre-determined current level prior to
a test.
INSTOperative / Read Amps –Fortesting the Instanta-
neousfunctionon AmptectorTripUnits.(Not functional
withMagnumDS trip units.)
SHORTDELAYOperative/Read Amps –Fortestingthe
ShortDelay function.
GROUNDTEST – For testing the Ground Fault function.
EXT.AM – Allows for connection of an external ammeter
to read current levels. Jumper must be installed when not
usingexternalammeter.
CIRCUITSELECTOR -PermitscheckingofallTripUnit
phaseinputcircuits.Sinceallfeed into a common pickup
andtiming circuit, it isonly necessary to use one phase to
test all the solid state circuitry functions. It is only neces-
sary to use one circuit function (e.g., long delay pickup) to
verify that each phase (A, B, and C) performs similarly.
TIMERON/OFF –The timer isusedtocalculateand display
the time-delay functions of theTrip Unit.
RESET (Timer) - Resets the timer after a test.
HI / LO AMPS – Selects the “level” of current to be in-
jected. (LOAMPS is typicallyforchecking Long Delay
PickuporGroundFaultPickup,and HIAMPSis forchecking
ShortDelay PickuporInstantaneous Level)
CURRENTADJUSTMENT –Adjuststhesecondarycurrent
injected into theTrip Unit.
2.1.2 TESTKIT ADAPTER
TheMagnum DSTestKitAdapter (8779C02G04) isusedto
connecttheTest Kit’s11-pinplugtotheMagnumDS
Digitrip Trip Unit 14-pin test port. In additon, the Auxiliary
PowerModule (PRTAAPM),whichispermanently con-
nected to the Adapter, must be connected to a 120V, 50/
60 HZ source to supply control power to theTrip Unit.(see
Figure2)
2.1.3 ZONE INTERLOCK SHORTING PLUG
TheZoneInterlockShorting Plug (8779C02G06) is
requiredwhenthebreakeris removed from the switchgear
cell for testing.The Shorting Plug must be installed on the
breakersecondarycontacts to defeat zone-interlock
wiring.(seeFigure3)
2.1.4 TEST KIT OPERATION GUIDELINES
To minimize thermal stress on theTest Kit andTrip Unit,
hold CALIB (momentary)toggle switch for no more than15
to 20 seconds at a time.
Ifcurrent persists after the testis complete, use STOP
switch to turn off the current.
When checking settings on theTrip Unit, the general
procedure is to start with the high current settings and
work down to the lowest current setting. This avoids
unnecessarydialchanges after calibration.

I.L. 32-693 A

Effective September 1998
The output current is a function of the line voltage, which
mustbesinusoidaland have good regulation.
If the Test Kit RESET lamp will not light, check to make
sure that no trip LED’s are lit on theTrip Unit. If so, press
the “trip reset” pushbutton on the face of the Trip Unit.
2.2 CIRCUITBREAKERINFORMATION
2.2.1 TRIPUNITTOLERANCEBANDS
Long DelayTimes of the Trip Unit are top of band,
thereforeexpect shorter times whentesting.
Short Time, Instantaneous, and Ground Fault values
are mid-band, which have +/- 10% tolerance.
2.2.2 TRIPUNITTESTGUIDELINES
Testing of the Trip Unit must be performed with the Trip
Unitproperlyinstalled inthebreaker.
The long time function has a memory circuit with a reset
time of 36 times the long delay time setting;i.e., for a LDT
settingof4 seconds the reset timeis144 seconds (36x4).
Therefore, for long delay time tests, there must be a time
delay greater than the calculated reset time or the ac
control power to the Trip Unit must be interrupted between
tests to clear the memory circuit.To do this, remove the ac
supplytotheAuxiliaryPowerModuleratherthandiscon-
necting the plug from theTest Kit Adapter.A thermal
memory jumper may need to be repositioned to the
“inactive”position to disable the thermal memory.This
jumper is shipped from the factory in the “active” position.
If a trip function LED on the Trip Unit is lit prior to a test,
press the “trip reset”pushbutton on theTrip Unit.
Whenbench testing a breaker wired forzone interlock
applications,shortingplug 8779C02G06mustbeinstalled
per Figure 5.

4.5 CHECKING LONG DELAYTIME (L.D.T.)
(SEE SECTION 2.2.2 REGARDING THETRIP UNIT’STHERMAL MEMORY
CIRCUIT)
1. Set theTest Kit as follows:
1A. TIMER switch to “OFF”.
1B. HI-LO AMPS switch to “HI AMPS”.
1C. CIRCUIT SELECTOR switch to “A”.
1D. CURRENTADJUSTMENT to“ZERO”.
2. If equipped, set Short Delay and Instantaneous
Pickups onTrip Unit to maximum (or off) to prevent
trip of the breaker by these functions.
3. Set desired Long Delay Pickup and Long DelayTime
onTripUnit.
4. Toggle CALIB switch to “CALIB”position and increase
currentontester,using CURRENTADJUSTMENT ,to6X
LDPUcurrent setting. (Donotholdin the “CALIB”

5. Push RESET button.
6. Turn TIMER “ON”. IfTIMERdoesnotreadzero,push
manual RESET buttonon TIMER .
7. Push TEST button. TIMER willstopwhenTripUnit trips
the breaker.Timer should read less than the dial
setting but not under 2/3 of the setting;e.g., if set at
24,it should be morethan 16 seconds butless than 24
seconds.NOTE:I2t= CONSTANT,therefore,trip time
at a current other than 6 (In) is calculated as follows:
(6 / z)2X (Long Delay Time) =Trip Time at z current,
where z = multiples of LDPU at which test current is
applied. Example:LongDelayTimeSetting = 24
seconds. Thenfor3times LDPU current setting
applied, the Long DelayTripTime would be as fol-
lows:
(6 / 3)2X (24 seconds) = 96 second Long Delay Time
at3LDPU.Remember touse5amperestimes LDPU
setting to set the tester current.
4.6 CHECKINGINSTANTANEOUS(IFAPPLICABLE)
1. SetLongDelay Pickup and Timetomaximumandset
ShortDelayPickuptoM1setting,sothatthesefunc-
tions do not trip the breaker.
2. Set desired Inst.pickup on theTrip Unit. Note:Pickup

8. For pickup values seeTable 1 below. Note that the
pickupvaluesshownontheTest Kit are insecondary
amperes.To convert theTest Kit reading to primary
values, multiply ammeter readings by In / 5 .
(1)Examples:
(a) Assume It= 1.2amps, In= 200, pickup setting =
.25, then: Ig= 1.2 x 200/5 = 48 primary amperes.
Table 1 shows expected value of 1.25 amperes.1.2
amperes is within the + 10% tolerance.
Forreferencepurposes,Table2 shows primary

ShortDelayTime. This function is provided asa
standard feature on all MagnumTrip Units. To test the
ShortDelayTime when the breaker is removed
beyondthe test position intheswitchgear,the zone
interlock shorting plug must be utilized (see Figure 5).
Without this, all Short Delay Time values will be
minimum.
1. DialShortDelayandLong DelayPickuponTripUnitas
desired. Note:2.5 timesthe short delay pickup setting
shouldnot exceedthecapability of theTestKit
(approx. 50 amperes) . i.e. Maximum short delay
pickup (Ir)= 4. Note that the Short Delay Pickup (Ir) is
afunctionof the Long Delay Setting times theShort
DelayPickupsetting.
2. SetLong Delay Time to maximum,andInstantaneous

(1) For the Digitrip 1150, settings are non-discrete, and may fall between the values listed above. The corresponding pickup
values must then be calculated. (Igx In, max 1200A)
(2) Except as noted, tolerances on pickup levels are ± 10% of values shown in chart.

Figure1.TestKit Controls and Legend
1 POWER ON/OFF – Turns on power to the Test Kit.
2 STOP – This switch manually cuts off the test current to
the Trip Unit.
3 LONG DELAY PICKUP - This light is not functional for
Magnum DS trip units.
4 TEST – Starts the test.
5 RESET – Resets theTest Kit after a test.
6 CALIB – Used in conjunction with CURRENT ADJUST
allowing for setting a pre-determined current level prior to a
test.
7 INST Operative / Read Amps – For testing the Instanta-
neous function on Amptector Trip Units. (Not functional with
Magnum DS trip units.)
8 SHORT DELAY Operative / Read Amps – For testing the
Short Delay function.
9 GROUND TEST – For testing the Ground Fault function.

10 EXT.AM – Allows for connection of an external ammeter
to read current levels. Jumper must be installed when not
using external ammeter.
11 CIRCUIT SELECTOR - Permits checking of all Trip Unit
phase input circuits. Since all feed into a common pickup and
timing circuit, it is only necessary to use one phase to test all
the solid state circuitry functions. It is only necessary to use
one circuit function (e.g., long delay pickup) to verify that
each phase (A, B, and C) performs similarly.
12 TIMER ON/OFF – The timer is used to calculate and
display the time-delay functions of the Trip Unit.
13 RESET (Timer) - Resets the timer after a test.
14 HI / LO AMPS – Selects the “level” of current to be
injected. (LO AMPS is typically for checking Long Delay
Pickup or Ground Fault Pickup, and HI AMPS is for checking
Short Delay Pickup or Instantaneous Level)
15 CURRENTADJUSTMENT – Adjusts the secondary current
injected into the Trip Unit.
