Westinghouse | EL3003R

Description:

The Westinghouse EL3003R 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 industrial power distribution panels requiring high fault current mitigation. Maintenance teams, OEMs, and electrical system integrators use this component for retrofit, replacement, and upgrading protection levels in existing MCCB systems.

Applications:

The Westinghouse EL3003R is used in industrial manufacturing facilities, commercial electrical distribution systems, motor protection circuits, and heavy-duty switchboard assemblies where controlled fault interruption is required. It is typically paired with MCP-series circuit breakers to improve interrupting capacity in three-phase systems, ensuring safer operation of feeders, motors, and sensitive electrical equipment under high fault conditions.
