Siemens System 89 25A Motor Circuit Protector - 480V/3P
25A MCP | 480V/3P | Magnetic-Only Trip | Motor Branch Protection
This Siemens System 89 25A motor circuit protector MCC bucket provides magnetic-only instantaneous trip protection, optimized for safety and operational uptime. Rated at 480V and 25A, 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, delivering reliable performance under the most demanding load conditions. Deployed across semiconductor fabrication, renewable energy installations, and municipal utilities, the System 89 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.
