Product FAQs
4 answersWhat does the V suffix indicate in the HFD3125V catalog number?
The V suffix indicates that the breaker is calibrated for use in 50 degrees Celsius (122 degrees Fahrenheit) ambient temperatures, rather than the standard 40 degrees Celsius calibration.
Can the HFD3125V replace standard FD3125 breakers?
Yes, the HFD3125V shares the same physical F-frame dimensions as the standard FD3125 but offers a higher interrupting capacity (65kAIC at 480VAC compared to 35kAIC) and includes the 50 degrees Celsius calibration.
What is the difference between the HFD3125V and the FDC3125?
Both are 125A, 3-pole F-frame breakers, but the FDC3125 has a higher interrupting capacity of 100kAIC at 480VAC. The HFD3125V is rated for 65kAIC at 480VAC and includes a 50 degrees Celsius calibration.
Are the trip settings on the HFD3125V adjustable?
No, this breaker features a fixed thermal and fixed magnetic trip unit. It does not offer field-adjustable trip settings for overload or short-circuit protection.
