Built for commercial power distribution, this single-pole 25A breaker integrates into industrial motor control centers. The thermal-magnetic mechanism provides fixed LI trip responses. Featuring a bolt-on mounting style, it fastens securely into Eaton Series C panelboards. Facilities upgrading infrastructure can transition to the newer PDG21G0025TFFJ model. Capable of clearing 35kA faults at 277VAC, it maintains system stability. It carries an HACR rating and supports reverse feed.
What panelboards are compatible with the FD1025 circuit breaker?
This F-Frame Series C breaker is designed for bolt-on installation in Eaton Pow-R-Line C panelboards, switchboards, and motor control centers. It is also compatible with many vintage Westinghouse and Cutler-Hammer enclosures that accept F-Frame breakers.
Can the FD1025 replace older Westinghouse F-Frame breakers?
Yes, Eaton Series C F-Frame breakers like the FD1025 are direct replacements for obsolete Westinghouse, Cutler-Hammer, and Challenger F-Frame breakers, including the FDB and FD series. They share the same physical footprint, though you must verify that the interrupting ratings meet your current system requirements.
Are the load-side lugs included with the FD1025?
Yes, the FD1025 comes standard with load-side lugs installed. The standard terminal kit (catalog number 3T100FB) accepts 14 AWG to 1/0 AWG copper or aluminum wire.
Is the FD1025 rated for direct current (DC) applications?
Yes, the thermal-magnetic trip unit is suitable for DC systems up to 125VDC with a 10kAIC interrupting rating. When used in DC applications, the magnetic trip threshold is typically higher than in AC applications.
Does the FD1025 provide GFCI or AFCI protection?
No, the FD1025 is a standard thermal-magnetic molded case circuit breaker providing long-time and instantaneous (LI) overcurrent and short-circuit protection. It does not include ground fault or arc fault circuitry.
Does the FD1025 support reverse feeding?
Yes, standard Eaton Series C F-Frame breakers like the FD1025 do not have line and load restrictions and can be reverse fed if required by your application.

175amp molded case circuit breaker
The breaker we purchased was as advertised. The breaker fit perfectly. We purchased reconditioned breaker and it seems to be working properly, accordingly to the golf course maintenance team that supervises the irrigation system.
Next day shipping came quickly even though the 4th of July was coming.
I wish it came with new installations hardware but that isn’t a deal breaker.
