Product FAQs
6 answersAre Eaton, Cutler-Hammer, and Westinghouse HFB3060 breakers interchangeable?
Yes. Eaton acquired the Westinghouse electrical distribution division in 1994. Breakers carrying the HFB3060 catalog number under the Westinghouse, Cutler-Hammer, or Eaton brands share the exact same physical dimensions and electrical characteristics.
What is the modern replacement for a legacy Westinghouse HFB3060?
The direct modern equivalent is the Eaton Series C HFD3060. The HFD is an F-Frame breaker that shares the same footprint as the legacy HFB, allowing it to mount into existing panelboards without requiring special retrofit kits.
What panelboards accept the HFB3060 circuit breaker?
This bolt-on F-Frame breaker is designed to install directly onto the busbars of legacy Westinghouse FDP panelboards, modern Eaton Pow-R-Line C panelboards, and compatible industrial switchboards.
What does the Mark 75 designation indicate on this breaker?
Mark 75 is a legacy Westinghouse trade name used to identify their line of high interrupting capacity circuit breakers. On the HFB3060, this denotes an elevated fault current rating, providing 65kA of interrupting capacity at 240VAC and 25kA at 480VAC.
Can the HFB3060 be applied in DC electrical systems?
Yes. In addition to standard AC ratings, this thermal magnetic breaker is rated for DC applications, providing up to 20kA of interrupting capacity at 250VDC.
Does the HFB3060 mount to a standard DIN rail?
No. This is a bolt-on molded case circuit breaker designed to bolt directly to the busbar in commercial and industrial panelboards. It cannot be mounted to a DIN rail.
