Siemens 8PX3 250A Motor Circuit Protector - 480V/3P
250A MCP | 480V/3P | Magnetic-Only Trip | Motor Branch Protection
This Siemens 8PX3 250A motor circuit protector MCC bucket provides magnetic-only instantaneous trip protection, precision-built for demanding environments. Rated at 480V and 250A, 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, offering drop-in replacement compatibility for quick retrofits. Deployed across oil and gas operations, food processing plants, and automotive assembly lines, the 8PX3 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.
