Built to handle extreme thermal conditions, this 225A three-pole breaker features a specialized 50°C ambient calibration for hot industrial and marine environments. The bolt-on design mounts firmly into Eaton Series C panelboards, switchboards, and motor control centers. It provides exceptional 100kAIC interrupting capacity at 480VAC to isolate severe electrical faults. Standard features include current-limiting operation, non-interchangeable thermal-magnetic trip, and an HACR rating.
What does the "V" suffix in the FDC3225V catalog number indicate?
The "V" suffix indicates that the breaker's thermal-magnetic trip unit is calibrated for a 50 degrees Celsius (122 degrees Fahrenheit) ambient temperature, rather than the standard 40 degrees Celsius calibration.
Can I use the Eaton FDC3225V to replace an older Cutler-Hammer FDC3225V?
Yes. Eaton acquired Cutler-Hammer, and modern Series C F-Frame breakers are identical, direct replacements for legacy Cutler-Hammer models sharing the same catalog number.
Is the FDC3225V suitable for HVAC applications?
Yes, this breaker carries an HACR (Heating, Air Conditioning, and Refrigeration) rating, making it approved for protecting commercial cooling and HVAC equipment.
Can the FDC3225V be reverse fed?
Yes, this molded case circuit breaker supports reverse feed configurations, allowing line power to be connected to either the top or bottom terminals without compromising protection.
What does the "C" in the FDC prefix stand for?
In Eaton's Series C nomenclature, the "C" designates it as an ultra-high interrupting capacity breaker, capable of clearing faults up to 100kA at 480VAC. Standard and high-capacity F-Frame versions use the FD and HFD prefixes, respectively.
Are the trip settings on the FDC3225V adjustable?
No, this model features fixed thermal and fixed magnetic trip functions. Applications requiring adjustable long-time or short-time settings require an F-Frame breaker with an electronic trip unit, such as the FDCE3225.
Will this 225A breaker fit in the same space as a lower-amperage F-Frame breaker?
Yes. All Eaton Series C F-Frame breakers share identical physical dimensions and mounting footprints. This allows the 225A FDC3225V to fit in the same panelboard space as a 15A or 100A F-Frame breaker.
