Eaton / Cutler-Hammer HKD3200 Molded Case Circuit Breaker

This Series C K-Frame breaker is engineered to mount directly into Eaton and legacy Cutler-Hammer panelboards, switchboards, and motor control centers.

Yes, standard pressure line and load terminals are included with the breaker. They are AL/CU rated, supporting both aluminum and copper conductors sized from 3 AWG up to 350 kcmil.

Yes. Eaton acquired the Cutler-Hammer and Westinghouse distribution equipment lines. The modern Series C HKD3200 is a direct drop-in replacement for older Westinghouse breakers sharing the exact same catalog number.

The "H" in the HKD prefix indicates a high-interrupting capacity frame. The HKD3200 provides a 65 kAIC rating at 480 VAC, whereas the standard KD3200 is only rated for 35 kAIC at 480 VAC. Both share the exact same physical K-Frame dimensions.

The magnetic short-circuit pickup is field adjustable. On this 200A frame, the setting typically ranges from 5 to 10 times the continuous current rating, allowing electricians to set the instantaneous trip anywhere from 1000A to 2000A to properly coordinate with system inrush.

Yes. Series C K-Frame thermal-magnetic breakers that use standard, non-interchangeable trip units are approved for reverse feed applications. Always ensure the circuit is fully de-energized and follow standard safety isolation procedures during installation.

When utilized in direct current applications up to 250 VDC, multiple poles must be wired in series. The exact wiring configuration depends on whether the system uses a grounded or isolated load design.
