Eaton / Cutler-Hammer FDC2050 Molded Case Circuit Breaker

This F-Frame breaker is designed for Eaton Series C Panelboards, Pow-R-Line C Panelboards, switchboards, and motor control centers. It is a commercial and industrial molded case breaker and will not fit in standard residential BR or CH load centers.

The difference lies in their interrupting capacity. The FDC2050 is the ultra-high interrupting capacity version of the Series C F-Frame, rated at 100kAIC at 480VAC. In comparison, standard FD breakers are rated at 35kAIC, and HFD breakers are rated at 65kAIC at 480VAC.

Yes. Standard Eaton Series C F-Frame thermal-magnetic circuit breakers are suitable for reverse feed applications. They do not have line and load restrictions, allowing power to be supplied from either the top or bottom terminals.

Yes. Eaton acquired the Westinghouse distribution equipment division. The current Eaton or Cutler-Hammer Series C FDC2050 is the exact same form, fit, and function as the older Westinghouse FDC2050.

Yes. The FDC series utilizes a patented contact design with high-speed blow-open action. This provides current-limiting performance, which helps reduce let-through energy and protects downstream equipment during massive fault currents.

The standard lugs on this 50A breaker accept wire gauges from 14 AWG up to 1/0 AWG. Always torque the terminal connections to the manufacturer specifications printed on the breaker label before energizing the circuit.

No. This breaker features a fixed thermal and fixed magnetic trip unit. The long-time (overload) and instantaneous (short-circuit) trip functions are factory set for 50 amps and cannot be adjusted in the field.

Yes, this thermal-magnetic breaker is rated for up to 250VDC with an interrupting capacity of 22kAIC. When applying it in DC circuits, ensure your system design aligns with Eaton guidelines for wiring 2-pole breakers in DC configurations.
