H- and J-frame Electronic Motor Circuit Protectors
PowerPact H- and J-frame electronic Motor Circuit Protectors (MCP) are magnetic-only
instantaneous-trip circuit breakers. They are designed to offer short circuit protection and
are National Electrical Code (NEC) compliant when installed as part of a combination
controller having motor overload protection. MCP circuit breakers accept the same
accessories and terminals as the equivalent thermal-magnetic circuit breakers.
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.

Based on 2005 NEC Table 430.52.
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.”
.5–5
Based on 2005 NEC Table 430.250.
Per NEC 430.3, part-winding motors should select two circuit breakers, each at not more than one-half the
allowable trip setting for the horsepower rating. The two circuit breakers should operate simultaneously as a
disconnecting means per NEC 430.103.
Listed voltages are rated motor voltages. Corresponding system voltages are 200 Vac, 220–240 Vac, 440–480
Vac and 550–600 Vac. Select wire and circuit breakers based on horsepower rather than nameplate full-load
current per NEC 430.6 (A) for general motor applications.
