Built for high-temperature applications, the Eaton HFD3015V is a 3-pole, 15-amp molded case circuit breaker. It features a specialized 50°C ambient calibration, making it exceptionally well-suited for marine environments and industrial facilities. This bolt-on MCCB fastens securely into Eaton Series C and Pow-R-Line panelboards, as well as compatible switchboards. Delivering 65kAIC at 480V, it provides robust thermal-magnetic (LI) protection against overloads and short circuits.
What does the "V" suffix in the HFD3015V catalog number indicate?
The "V" suffix indicates a 50 degree Celsius ambient temperature calibration, designed to prevent nuisance tripping in high-heat environments like marine or industrial facilities. Note that Eaton breakers with this special 50 degree Celsius calibration are not UL listed.
What is the difference between the HFD3015 and the HFD3015V?
The standard HFD3015 is calibrated for a 40 degree Celsius ambient temperature and carries a standard UL listing. The HFD3015V features a 50 degree Celsius calibration for high-heat environments but does not carry a UL label due to this specialized calibration.
Can this breaker replace legacy Westinghouse F-Frame circuit breakers?
Yes, Eaton Series C F-Frame breakers are direct mechanical and electrical replacements for older Cutler-Hammer and Westinghouse F-Frame breakers with matching pole counts and electrical ratings.
Is the HFD3015V suitable for reverse feed applications?
Yes, Eaton Series C F-Frame circuit breakers are suitable for reverse feed use, allowing line and load connections to be swapped if required by the enclosure layout.
How is the HFD3015V wired for 250VDC applications?
When applying this 3-pole breaker in a 250VDC system, Eaton requires wiring two of the poles to safely interrupt the direct current fault energy. Consult the manufacturer wiring diagrams for proper pole configuration.
Does the HFD3015V include panelboard mounting hardware?
No, this bolt-on breaker does not include the bus mounting hardware. The necessary screws and connectors are typically provided with the Eaton Series C or Pow-R-Line panelboard chassis or the specific bus kit.
What safety precautions should be taken before installing the HFD3015V?
Always ensure the panelboard is completely de-energized and follow standard lockout and tagout procedures before installing or servicing the circuit breaker. Verify the absence of voltage using a properly rated multimeter.
