Westinghouse MCP0322R Motor Circuit Protector

Description:

The Westinghouse MCP0322R Motor Circuit Protector is a magnetic-only molded case motor protection breaker used in industrial motor control and automation systems. Commonly installed in motor control centers, combination starters, industrial machinery, and HVAC equipment requiring short-circuit protection for electric motors. Maintenance electricians, control engineers, and industrial automation technicians use this motor circuit protector for replacement, retrofit, or motor protection system maintenance. Unlike standard thermal-magnetic breakers, the MCP series provides magnetic short-circuit protection only and must be used with separate motor overload protection devices.

Applications:

The Westinghouse MCP0322R motor circuit protector is commonly used in industrial automation and motor control systems to protect three-phase motors, starters, and branch circuits from high fault current conditions. It is installed in manufacturing facilities, conveyor systems, pumps, compressors, and industrial process equipment where reliable motor short-circuit protection and fast magnetic trip response are required. The breaker is designed for use in combination motor controller applications with external overload relays or heater elements.
