Eaton / Cutler-Hammer FDC3050 Molded Case Circuit Breaker

Yes. Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines. The Eaton FDC3050 is a direct replacement for legacy Westinghouse and Cutler-Hammer FDC3050 breakers.

This unit mount breaker is designed for installation in Eaton Series C panelboards, switchboards, motor control centers, and standard F-frame enclosures.

Yes. Standard thermal-magnetic Series C F-frame breakers like the FDC3050 are suitable for reverse feed applications, as they are not restricted by line and load directional markings.

The standard line and load lugs on the 50A FDC3050 accept 14 AWG to 1/0 AWG copper or aluminum wire.

In the Eaton Series C family, the C designates the ultra-high interrupting capacity version of the F-frame. The FDC3050 provides up to 200kAIC at 240VAC and 100kAIC at 480VAC, which is significantly higher than standard FD or high-interrupting HFD breakers.

Yes, it carries a DC rating of 250VDC with an interrupting capacity of 22kAIC. For specific DC applications, poles may need to be wired in series according to Eaton guidelines.

No. The FDC3050 features a standard thermal-magnetic trip unit with fixed long-time and instantaneous (LI) functions for overload and short-circuit protection. It does not include ground fault or arc fault circuitry.

The primary difference is the interrupting capacity. The FD3050 is the standard rating at 35kAIC at 480V, the HFD3050 is the high rating at 65kAIC at 480V, and the FDC3050 is the ultra-high rating at 100kAIC at 480V. All three share the same physical F-frame footprint.
