Product FAQs
6 answersWhat do the V and L suffixes mean in the HFB3015VL catalog number?
The V indicates the breaker is calibrated for a 50 degrees Celsius ambient temperature, rather than the standard 40 degrees. The L signifies that the breaker comes equipped with both line and load lugs, as standard F-frame breakers typically only include load-side terminals.
What is the direct replacement for the HFB3015VL?
The HFB3015VL is a legacy Mark 75 series breaker that has been replaced by the Eaton Series C HFD3015. If your application strictly requires the 50 degrees Celsius calibration and line-side lugs, you will need to specify the HFD3015VL to ensure those features are included.
Which panelboards are compatible with the HFB3015VL?
This bolt-on F-frame breaker is designed to fit into Westinghouse FDP panelboards, Eaton Pow-R-Line C panelboards, and legacy F-frame switchboards.
Why would an application require the 50 degrees Celsius calibration of the HFB3015VL?
A 50 degrees Celsius calibration is typically required for high-ambient temperature environments, such as boiler rooms, foundries, or specific industrial enclosures. This prevents the thermal trip element from nuisance tripping prematurely, which can happen if a standard 40 degrees Celsius breaker is used in extreme heat.
Can I use this Eaton breaker to replace an older Westinghouse HFB3015VL?
Yes. Eaton acquired the Westinghouse distribution equipment business. An Eaton or Cutler-Hammer branded HFB3015VL is an exact, direct replacement for a legacy Westinghouse breaker with the exact same catalog number.
Can I install the HFB3015VL in a standard residential loadcenter?
No. This is a bolt-on molded case circuit breaker designed specifically for commercial and industrial panelboards. It is not compatible with standard residential plug-on loadcenters.
