Siemens 8PX3 3A Motor Circuit Protector - 480V/3P
3A MCP | 480V/3P | Magnetic-Only Trip | Motor Branch Protection
This Siemens 8PX3 3A motor circuit protector MCC bucket provides magnetic-only instantaneous trip protection, proven in high-demand industrial settings. 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, supporting NFPA 70E compliance and workplace safety standards. 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.
