CFD63B150L - 150Amp Circuit Breaker

CFD63B150L - 150Amp Circuit Breaker

Keeping electrical distribution systems protected starts with using the right breaker for the application. The CFD63B150L 150 Amp 3 Pole Molded Case Circuit Breaker is designed for commercial and industrial power systems that require dependable overcurrent protection and high interrupting capacity. Built on the Sentron CFD6 frame, this breaker helps protect equipment, feeders, and distribution circuits from overloads and short-circuit events while providing the form, fit, and function needed for compatible existing installations.

Designed with a fuseless current-limiting construction, the CFD63B150L helps limit the effects of fault currents and supports the protection of connected electrical equipment. Its impressive interrupting ratings of 200kA at 240VAC, 200kA at 480VAC, and 100kA at 600VAC make it a practical choice for facilities where higher fault-current levels may be present.

Whether you're maintaining a manufacturing facility, servicing power distribution equipment, supporting an HVAC installation, or replacing a compatible breaker in an existing electrical system, the CFD63B150L is designed to deliver the ratings and configuration required for the job.
