Part of the proven Series C family, this 175A two-pole breaker provides robust long-time and instantaneous trip functions for commercial systems. It installs into standard Eaton panelboards, switchboards, and motor control centers requiring bolt-on F-Frame configurations. Rated for 65kAIC at 240V and 35kAIC at 480V, the unit features HACR certification and reverse feed capabilities. Note that this legacy model is officially replaced by the Power Defense PDG22G0175TFFJ with a retrofit kit.

Can the Eaton FD2175 be reverse fed?
Yes. Eaton Series C F-frame thermal-magnetic circuit breakers, including the FD2175, are suitable for reverse feed applications.
What is the difference between the FD2175 and the HFD2175 or FDC2175?
The difference is the interrupting capacity. The FD2175 is rated at 35kAIC at 480VAC, while the HFD2175 is rated at 65kAIC and the FDC2175 is rated at 100kAIC at 480VAC. All three share the same physical footprint and F-frame dimensions.

Can internal accessories like a shunt trip be added to the FD2175?
Internal accessories for Eaton Series C F-frame thermal-magnetic breakers, such as shunt trips and auxiliary switches, must be factory installed to maintain the breaker seal and UL label. They are typically mounted in the left pole.
Are the terminals on the FD2175 interchangeable with newer Eaton breakers?
Yes. The terminals on the Series C F-frame FD2175 are interchangeable with Eaton Power Defense Frame 2 (PD2) circuit breakers.

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.
