Current Limit-R - Current Limiting Circuit Breakers, Non-Fused Type



Westinghouse Current limmiter EL3 Circuit Breaker

Current Limit-R circuit breakers are designed to protect standard Westinghouse circuit breakers with interrupting ratings as low as 10 kA rms symmetrical on systems capable of delivering fault currents as high as 200kA rms symmetrical.  In such a system, the Current Limit-R main breaker and standard Westinghouse branch breaker closest to the fault operate together to limit the amount of let-through fault current.

These circuit breakers utilize the Westinghouse patented slot motor concept to provide higher interrupting capacities without using fuses.  Current Limit-R circuit breakers are UL listed, meet the NEC definition for a current limiting device, and are the same size as the comparable Tri-Pac circuit breakers.

Tri-Pac - Current Limiting Circuit Breakers, Fused Type


Westinghouse Tri-Pac Circuit Breakers LA 2 and 3 pole

Tri-Pac thermal magnetic circuit breakers provide higher interrupting capacities by utilizing integral current limiting fuses.  These circuit breakers can be used in commercial and industrial distribution systems where fault current may reach as high as 200 kA rms symmetrical.


Compact Tri-Pac circuit breakers are rated from 15 to 1600 amperes and can be applied as main breakers...and as protective breakers for feeder and branch circuits and other connected apparatus.


Overcurrents and low level faults are cleared by thermal action; normal faults cleared by magnetic action; and abnormal faults above an estimated value are cleared by the current limiting fuses.

Series C HMCP - Motor Circuit Protectors


Westinghouse Series C HMCP, MCP 3 Pole Circuit Breaker


HMCP motor circuit protectors provide the industry's most effective protection against low level faults.  A 15 ampere HMCP will open all phases and clear a fault less than one cycle - before the fault produces an arching condition that can cascade and cause potentially serious motor damage.


These devices, available in ratings of 150 to 600 amperes, incorporate several Series C Molded Case Circuit Breaker features including quick make - quick break action, dead front safety, trip indication, and proven reliability.


Protection settings are quickly and easily selected by the user and the HMCP will provide protective interruption of any current above the selected setting.
