Siemens Model 90 15A Motor Circuit Protector - 480V/3P
15A MCP | 480V/3P | Magnetic-Only Trip | Motor Branch Protection
This Siemens Model 90 15A motor circuit protector MCC bucket provides magnetic-only instantaneous trip protection, purpose-built for critical infrastructure. Rated at 480V and 15A, 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, providing superior arc flash protection and operator safety. Deployed across semiconductor fabrication, renewable energy installations, and municipal utilities, the Model 90 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.
