CFD63B250L - 250Amp Circuit Breaker

CFD63B250L - 250Amp Circuit Breaker

When dependable circuit protection is needed in an existing power distribution system, the CFD63B250L molded case circuit breaker delivers the ratings and compatibility required for a wide range of commercial and industrial applications. Rated at 250 amps and configured with three poles, this breaker is designed for three-phase electrical systems where maintaining the original equipment specifications is essential.

Built on the Sentron CFD6 frame, the CFD63B250L combines a fuseless current-limiting design with a non-interchangeable trip unit to help protect electrical equipment from overloads and short circuits. Its substantial interrupting capacity—200kA at 240VAC, 200kA at 480VAC, and 100kA at 600VAC—makes it suitable for installations where available fault currents demand significant protection. Whether you're supporting a manufacturing facility, commercial building, institutional campus, or heavy-duty electrical distribution system, this breaker is built to last and designed to provide the form, fit, and function needed for compatible replacement applications.

The breaker comes equipped with both line-side and load-side terminals, helping simplify installation and maintenance activities.
