Westinghouse Electric MCP33100R Circuit Breaker

The Westinghouse MCP33100R is a 3-pole, 100 A, 600 V circuit breaker designed for industrial motor control and branch-circuit protection in demanding environments. It uses a magnetic trip mechanism, panel-mount installation, screw-terminal connections, and enclosure compatibility with switchgear and distribution equipment, and is industrial-duty rated for three-phase operation at 50/60 Hz. Typical applications include HVAC systems, pump controls, packaging machinery, process automation, material handling equipment, OEM industrial control assemblies, and other equipment requiring reliable three-phase protection. Common replacements include Eaton HMCP050K2C, Allen-Bradley 140M-C2E-B100, and Square D FA34100.
