Allis Chalmers Marq 2 3A Motor Circuit Protector - 480V/3P
3A MCP | 480V/3P | Magnetic-Only Trip | Motor Branch Protection
This Allis Chalmers Marq 2 3A motor circuit protector MCC bucket provides magnetic-only instantaneous trip protection, engineered for maximum reliability. Rated at 480V and 3A, 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, allowing hot-swappable serviceability without de-energizing the MCC lineup. Deployed across semiconductor fabrication, renewable energy installations, and municipal utilities, the Marq 2 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.
