CFD63B175 - 175Amp Circuit Breaker

CFD63B175 - 175Amp Circuit Breaker

When your electrical systems depend on consistent circuit protection, having the correct breaker in place matters. The CFD63B175 is a 175 amp, 3-pole molded case circuit breaker built on the Sentron CFD6 frame, designed to provide overcurrent and short-circuit protection in commercial and industrial power distribution systems.

Featuring a non-interchangeable trip unit and fuseless current-limiting design, this breaker helps protect connected equipment while supporting the safe operation of electrical distribution systems.

Whether you're installing it in a manufacturing facility, commercial building, HVAC system, or power distribution assembly, this breaker is designed to provide the form, fit, and functional compatibility needed to keep existing systems operating as intended. Its compact footprint, included load-side terminals, and 50/60Hz operation make it a practical choice for a variety of three-phase electrical applications. Like many breakers built for demanding environments, the CFD63B175 was designed with long service life in mind and continues to be used in facilities that rely on dependable circuit protection.
