Product FAQs
8 answersWhat is the difference between the Eaton FD, HFD, and FDC circuit breakers?
The primary difference is the interrupting capacity. The FD is the standard interrupting breaker, the HFD is high interrupting, and the FDC is the extra-high interrupting, current-limiting version. All three share the same physical F-Frame dimensions and mount in the same Series C panelboards.
Is the FDC2125 circuit breaker current limiting?
Yes, the FDC series is a current-limiting molded case circuit breaker. Its design minimizes let-through energy during a fault, providing enhanced protection for downstream equipment.
Can the FDC2125 be reverse fed?
Yes, Eaton Series C F-Frame breakers, including the FDC2125, are reverse feed capable. They can be wired with the line connections on either the top or bottom terminals.
What wire sizes are accepted by the lugs on the FDC2125?
The standard lugs accept copper or aluminum wire ranging from 4 AWG to 4/0 AWG. Ensure proper torque specifications are followed during installation as outlined on the breaker faceplate.
Is this breaker suitable for DC voltage applications?
Yes, the FDC2125 is rated for use in DC systems up to 250VDC, with a direct current interrupting rating of 22kAIC.
What types of enclosures or panels are compatible with this breaker?
This unit-mount breaker is designed for use in Eaton Series C panelboards, switchboards, and motor control centers. It bolts directly to the chassis or mounting pan.
Does the FDC2125 have an interchangeable trip unit?
No, this breaker features a non-interchangeable, fixed thermal-magnetic trip unit. The long-time and instantaneous trip functions are factory set and cannot be modified or swapped.
Is the FDC2125 HACR rated?
Yes, this breaker is HACR rated, meaning it is approved for use with heating, air conditioning, and refrigeration equipment that requires this specific designation.
