Product FAQs
7 answersCan the HFD3045L replace older Westinghouse or Cutler-Hammer HFD breakers?
Yes. The Eaton Series C HFD3045L is backward compatible and serves as a direct replacement for older Westinghouse and Cutler-Hammer HFD breakers with the same 45A rating and 3-pole configuration.
What does the H in the HFD3045L part number indicate?
The H designates this as a high-interrupting capacity breaker. It provides a 100kAIC rating at 240VAC and 65kAIC at 480VAC, which is significantly higher than standard FD frame breakers.
Is the HFD3045L suitable for reverse feed applications?
Yes. This thermal-magnetic molded case circuit breaker is suitable for reverse feed installations.
What types of enclosures are compatible with the HFD3045L?
This F-frame breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers that accept unit-mount FD-frame breakers.
Is there a newer generation replacement for the Series C HFD3045L?
Yes. Eaton Power Defense (PDG) is the newest generation of molded case circuit breakers designed to replace legacy Series C FD and HFD breakers. Upgrading to the Power Defense platform requires updated Eaton mounting hardware.
Does the HFD3045L provide ground fault or equipment protection?
No. This breaker features standard long-time and instantaneous (LI) trip functions for overload and short-circuit protection. It does not include ground fault or equipment protection features.
Can I adjust the trip settings on the HFD3045L?
No. The HFD3045L features a fixed thermal and fixed magnetic trip unit. The overload and short-circuit trip points are factory set and cannot be adjusted in the field.
