RS Breakers & Controls carries an extensive inventory of new, reconditioned, and obsolete motor circuit protectors (MCPs) for industrial motor control. As part of our comprehensive circuit breakers offering, MCPs provide specialized motor branch circuit protection. All previously used units are tested to ANSI and CSA standards with a detailed test report and full 2-year warranty.
Motor circuit protectors are specialized circuit breakers designed specifically for motor branch circuit protection. Unlike standard thermal-magnetic circuit breakers, MCPs provide magnetic-only (instantaneous) trip protection without a thermal element. This design allows normal motor inrush currents to pass without nuisance tripping while providing fast response to short circuit faults. MCPs are typically used alongside contactors and overload relays, forming a complete motor branch circuit protection package.
Motor circuit protectors are critical circuit breakers that keep production lines running safely. A failed or incorrectly rated MCP can lead to nuisance tripping or fail to clear a short circuit fault. RS Breakers & Controls stocks these specialized circuit breakers across all major manufacturers and frame sizes.
Our technical team can help you match the correct motor circuit protector from our circuit breakers inventory to your motor’s full load amps and fault current levels.
