Product FAQs
7 answersWhat does the V suffix indicate in the HFD3040V catalog number?
The V suffix indicates the breaker is calibrated for a 50 degree Celsius ambient environment, rather than the standard 40 degree Celsius calibration. This prevents nuisance tripping in high-heat industrial settings.
Can the HFD3040V circuit breaker be reverse fed?
Yes. Eaton Series C F-Frame thermal magnetic circuit breakers, including the HFD series, are suitable for reverse feed applications.
Can this replace an older Westinghouse HFD3040V?
Yes. Eaton acquired the Westinghouse distribution equipment division and continued manufacturing the Series C line. This breaker is a direct replacement for legacy Westinghouse and Cutler-Hammer breakers with the exact same catalog number.
What is the difference between the standard HFD3040 and the HFD3040V?
Both are 40A, 3-pole F-Frame breakers with identical physical dimensions and interrupting ratings. The HFD3040 is calibrated for standard 40 degree Celsius environments, while the HFD3040V is calibrated for 50 degree Celsius environments.
Are line and load lugs included with this breaker?
Yes, the standard HFD3040V comes complete with factory-installed line and load side lugs ready for wire termination.
Is the HFD3040V interchangeable with standard FD or FDC breakers?
It shares the exact same physical F-Frame dimensions as standard FD and FDC breakers. It will mount in the same Series C panelboard spaces, though the interrupting ratings and temperature calibrations will differ.
Can the trip settings on the HFD3040V be adjusted?
No. This breaker features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous trip functions are factory set and cannot be modified in the field.
