INCOMING LINE CIRCUIT BREAKER KIT
For Regenerative MaxPak Plus Controllers
Model Numbers 23C301Ć23C304
Assembly Drawing 705390Ć3
The equipment described below should be installed only by qualified electrical maintenance personnel familiar
with the construction and operation of the equipment and the hazards involved.
DESCRIPTION
Circuit breaker kits provide an aĆc input line circuit
breaker and throughĆtheĆdoor operating mechanism
for installation into regenerative MaxPak Plus controlĆ
lers. The circuit breaker provides additional fault protecĆ
tion for the drive by means of its magnetic trip device.
It also serves as a means to disconnect and lock out inĆ
coming aĆc line power. A throughĆtheĆdoor operator alĆ
lows operation of the circuit breaker from outside the
controller cabinet and provides a mechanical door inĆ
terlock as well.
Each kit is supplied complete with its circuit breaker
premounted on a sheet metal plate for installation in
front of the armature contactor and circuit breaker, a
load side wiring harness, an insulating side shield
(where required) to provide personnel protection by
preventing accidental contact with armature buswork
hidden by the kit, and top and bottom mounting brackĆ
ets. All hardware required for installation is provided
with each kit.
SPECIFICATION
The appropriate circuit breaker kit should be seĆ
lected on the basis of controller horsepower and voltĆ
age per Table 1. Table 1 also provides breaker frame
size, current and trip setting specifications for each kit.

ALLOWABLE AVAILABLE
FAULT CURRENT
The regenerative MaxPak Plus controller, furĆ
nished without an input circuit breaker, has a short
circuit protection system designed to operate on
plant power supplies with maximum allowable availĆ
able symmetrical RMS fault currents as listed in
Table 5 on page 10 of I/M DĆ3851. Do not attempt to
operate the MaxPak Plus controller on plant power
supplies with available short circuit currents in exĆ
cess of these allowable maximums.
The addition of these incoming line circuit breakĆ
er kits do not reduce the allowable available short
circuit. Table 5 on page 10 of I/M DĆ3851 lists allowĆ
able short circuit currents for MaxPak Plus controlĆ
lers. Data in Table 5 is applicable either with or withĆ
out addition of these circuit breaker kits.
INSTALLATION
(Refer to Assembly Drawing 705390Ć3)
WARNING
BEFORE ATTEMPTING TO INSTALL THIS MAXĆ
PAK PLUS MODIFICATION KIT, DISCONNECT
AND LOCK OUT ALL SOURCES OF INCOMING
POWER TO THE CONTROLLER CABINET.
