Westinghouse ELC3050R Current Limiter 50A 600V 3P F Frame 50 Amp 3 Pole HMCP

Description:

The Westinghouse ELC3050R Current Limiter is used in industrial motor circuit protection systems as a high-capacity current-limiting attachment for HMCP and MCCB assemblies. Commonly installed in switchgear, motor control centers, and industrial power distribution panels requiring enhanced short-circuit interruption capability. Maintenance teams, OEMs, and electrical system integrators use this component for retrofit, upgrade, and replacement of protection systems in heavy-duty electrical installations.

Applications:

The Westinghouse ELC3050R is used in industrial manufacturing plants, commercial electrical distribution systems, motor protection circuits, and heavy-duty switchgear assemblies where high fault current levels must be safely controlled. It is typically paired with HMCP or MCP breaker frames to increase interrupting capacity in three-phase systems, ensuring reliable protection of motors, feeders, and critical industrial equipment.
