CFD63B250 - 250Amp Circuit Breaker

CFD63B250 - 250Amp Circuit Breaker

The CFD63B250 is a 250 amp, 3-pole molded case circuit breaker designed for use in commercial and industrial electrical distribution systems. Built on the Sentron CFD6 frame, this breaker is commonly installed in switchgear, distribution equipment, motor control centers, and other power management applications where maintaining original equipment specifications is essential. When your replacing an existing breaker, matching the frame size, amperage rating, interrupting capacity, and terminal configuration helps ensure compatibility with the existing electrical system.

This CFD6 molded case circuit breaker features a non-interchangeable trip unit and fuseless current-limiting design to provide circuit protection during overload and short-circuit conditions. With interrupting ratings of 200kA at 240VAC, 200kA at 480VAC, and 100kA at 600VAC, the CFD63B250 is suitable for applications where available fault current levels require high interrupting capacity. Rated for 50/60Hz operation and HACR applications, it includes load-side terminals and is designed for use in environments with an operating temperature of 40°C. Built to last, the CFD63B250 provides the form, fit, and functional characteristics required for compatible Sentron CFD6 installations and replacement projects.
