Industrial SPHM3RM02R5 Din Rail Circuit Breaker

The Cutler-Hammer SPHM3RM02R5 functions as a three-pole DIN rail circuit breaker engineered specifically for three-phase power protection in industrial control assemblies throughout warehouses and manufacturing plants. Cataloged under the SPHM series, this unit operates continuously at 2.5 Amps and accommodates system voltages ranging between 277 volts and 480 volts AC for compatible network topologies. Designed for mounting onto standard aluminum or steel DIN rails, the device provides immediate fault isolation through a trip mechanism sensitive to both short circuits and prolonged overloads to protect downstream wiring insulation. Technicians specify this exact OEM part to restore functionality to aging switchboards where precise pole counts and rated breaking capacities align with historical NEMA equipment standards and modern safety compliance regulations.
