CFD63B080 - 80Amp Circuit Breaker

CFD63B080 - 80Amp Circuit Breaker

The CFD63B080 is an 80 amp, 3-pole molded case circuit breaker built on the CFD6 Sentron frame and intended for use in commercial and industrial power distribution systems. It provides overcurrent and short-circuit protection for three-phase electrical equipment while offering the high interrupting ratings often required in facilities with substantial available fault current.

This breaker features a non-interchangeable trip unit and a fuseless current-limiting design, helping protect downstream equipment when fault conditions occur. With interrupting capacities rated at 200kA at 240VAC, 200kA at 480VAC, and 100kA at 600VAC, it can be applied in a wide range of distribution and equipment protection applications.

Whether installed in a switchboard, panel, motor control system, or HVAC-related application, this breaker is built for long service life and dependable operation.

For facilities maintaining existing electrical infrastructure, the CFD63B080 is often selected as a form-fit-function replacement where compatibility with the CFD6 Sentron frame is required.
