Allis Chalmers Marq 1 20A Motor Circuit Protector - 480V/3P
20A MCP | 480V/3P | Magnetic-Only Trip | Motor Branch Protection
This Allis Chalmers Marq 1 20A motor circuit protector MCC bucket provides magnetic-only instantaneous trip protection, designed for continuous duty cycles. Rated at 480V and 20A, it is specifically designed for motor branch circuit protection per NEC Article 430. Unlike thermal-magnetic breakers, this MCP offers precise magnetic trip settings that coordinate with downstream overload relays, ensuring code-compliant installations with streamlined wiring. Deployed across building automation systems, conveyor networks, and packaging lines, the Marq 1 MCP bucket ensures Type 2 coordination when paired with compatible contactors and overload devices. Each unit ships factory-wired and tested for immediate plug-in installation with UL 508A and UL 845 compliance.
