Product FAQs
7 answersWhat panels or distribution equipment can I install the HFD3045 in?
This F-Frame breaker is engineered for Eaton Series C panelboards, switchboards, and motor control centers. It is also compatible with legacy Westinghouse and Cutler-Hammer distribution systems that accept F-Frame breakers.
What is the difference between the FD3045 and the HFD3045?
The H designation stands for high-interrupting capacity. While the standard FD3045 provides 35kAIC at 480VAC, the HFD3045 delivers 65kAIC at 480VAC and 100kAIC at 240VAC. Both share the exact same F-Frame physical footprint, meaning the HFD3045 can directly replace an FD3045 when higher fault current ratings are required by your system study.
Can the HFD3045 replace an older Westinghouse or Cutler-Hammer breaker?
Yes. Eaton acquired the distribution equipment division of Westinghouse and later phased out the Cutler-Hammer name. The modern Eaton HFD3045 serves as a direct, manufacturer-approved replacement for legacy Westinghouse or Cutler-Hammer HFD3045 breakers.
Do I need to purchase lugs separately for this breaker?
No, the HFD3045 comes equipped with factory-installed line and load lugs. These terminals are rated for 14 AWG to 1/0 AWG wire and are tested for use with both copper and aluminum conductors.
Is this a bolt-on or plug-on circuit breaker?
The HFD3045 is a panel-mount, bolt-on circuit breaker designed to be bolted to the bus assembly in commercial or industrial panels. It is not compatible with plug-on residential load centers or DIN rail enclosures without specialized adapter kits.
Does this breaker provide equipment ground fault or arc fault protection?
No. The HFD3045 utilizes a standard thermal magnetic trip unit featuring long-time and instantaneous (LI) functions to protect against overloads and short circuits. It does not contain GFCI, GFP, or AFCI safety mechanisms.
What is the direct replacement for this breaker in the Eaton Power Defense line?
The modern equivalent for the HFD3045 in the Eaton Power Defense series is catalog number PDG23M0045TFFJ. When migrating from Series C to Power Defense, verify if your specific panelboard requires updated mounting hardware to accommodate the newer frame design.
