Westinghouse MCP0358C Molded Case Motor Circuit Protector

The Westinghouse MCP0358C Molded Case Motor Circuit Protector is a three-pole, 7 A device designed to provide short-circuit protection for industrial motors and associated electrical equipment. It features a molded-case housing with a magnetic trip, 600 VAC rating, and 50/60 Hz compatibility, and is intended for panel mounting using screw terminal connections in three-phase systems. This industrial-duty protector is used in motor control centers, HVAC systems, conveyor lines, packaging machinery, process automation equipment, material handling systems, and OEM control panels where reliable motor short-circuit protection is required. The MCP0358C designation identifies its Westinghouse lineage and its role as a molded case motor circuit protector suitable for installations in motor control centers and other industrial panels. For replacements or upgrades, common substitutions include Eaton HMCP007A0C, Allen-Bradley 140M-C2E-B07, and Square D FA34007.
