50A MCP | 480V/3P | Magnetic-Only Trip | Motor Branch Protection
This Klockner Moeller Model 90 50A motor circuit protector MCC bucket provides magnetic-only instantaneous trip protection, built to withstand harsh industrial conditions. Rated at 480V and 50A, 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, reducing downtime and improving operational efficiency. Deployed across chemical processing, power generation, and wastewater treatment plants, 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.
