Westinghouse EL3007R Molded Case Circuit Breaker

Description:

The Westinghouse EL3007R Circuit Breaker is used in industrial molded case circuit breaker systems as a current-limiting accessory for enhanced fault protection. Commonly installed in MCC (motor control centers), switchgear assemblies, and industrial power distribution systems requiring high interrupting capacity and coordinated protection. Maintenance teams, OEMs, and electrical integrators use this part for retrofit, replacement, and system upgrades in heavy-duty electrical installations.

Applications:

The Westinghouse EL3007R is used in industrial power systems, manufacturing plants, heavy machinery panels, motor protection circuits, and commercial electrical distribution networks where high fault current conditions require controlled interruption. It is typically paired with MCP-series breakers to improve short-circuit performance, ensuring safer operation of three-phase distribution equipment and critical loads in demanding environments.
