J-Frame Motor Circuit Protector
JJL36250M75
PowerPact electronic Motor Circuit Protectors (MCP) are magnetic-only instantaneous-
trip circuit breakers. Designed to offer short circuit protection, they are National Electrical
Code (NEC) compliant when installed as part of a combination controller having motor
overload protection.
•
Sensor ratings from 30–1200 A at up to 600 Vac
•
Electronic trip units with adjustable instantaneous trip ranges
•
3-pole available in unit mount and I-Line construction
•
Accept the same accessories and terminals as equivalent PowerPact circuit breakers
•
UL, CSA, IEC certified and CE marked for global acceptance
Selection
Determine the hp rating from the nameplate of the motor. Select a MCP with an ampere
rating recommended for the hp and voltage involved. When using the automatic settings
the MCP microprocessor automatically adjusts the trip settings for both current and time
to align with the start-up characteristic for the motor type, whether it is a standard or
energy-efficient motor. This includes a dampening means to accommodate a transient
motor in-rush current without nuisance tripping of the circuit breaker.

MINIATURE AND MOLDED CASE
CIRCUIT BREAKERS
[1] Based on 2017 NEC Table 430.52.
[2] See NEC Exception No. 1 to Table 430.52. The NEC 1300% maximum setting may be inadequate for instantaneous trip circuit breakers to withstand current surges typical of the
magnetization current of autotransformer type reduced voltage starters, or open transition wye-delta starters during transfer from “start” to “run,” constant hp multi-speed motors, and motors
labeled “high efficiency.”
