WESTINGHOUSE,EL3150R,CURRENT LIMITER 150AMP 3POLE 600VAC

Description:

The Westinghouse EL3150R Current Limiter is used in industrial molded case circuit breaker systems to provide enhanced short-circuit current limiting protection. Commonly installed in motor control centers, switchgear assemblies, and heavy-duty electrical distribution panels requiring high fault current interruption capability. Maintenance teams, OEMs, and system integrators use this component for retrofit, replacement, and upgrade applications in industrial and commercial power systems.

Applications:

The Westinghouse EL3150R is used in industrial manufacturing plants, commercial electrical distribution networks, and heavy equipment power systems where high available fault current must be safely controlled. It is typically paired with MCP-series and compatible MCCB frames to increase interrupting capacity in three-phase 600V systems, ensuring safe operation of feeders, motors, and critical loads under short-circuit conditions.
