Siemens Marq 21 10A Motor Circuit Protector - 600V/3P
10A MCP | 600V/3P | Magnetic-Only Trip | Motor Branch Protection
This Siemens Marq 21 10A motor circuit protector MCC bucket provides magnetic-only instantaneous trip protection, crafted for mission-critical applications. Rated at 600V and 10A, 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, simplifying inventory management with standardized form factors. Deployed across semiconductor fabrication, renewable energy installations, and municipal utilities, the Marq 21 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.
