Product FAQs
7 answersIs the FDB3225 a direct replacement for older Westinghouse FDB breakers?
Yes. Eaton acquired the Westinghouse distribution equipment division, and the Series C FDB3225 is a direct, drop-in replacement for legacy Westinghouse FDB3225 breakers.
What is the modern Eaton replacement for the FDB3225?
The FDB3225 is being transitioned to the Eaton Power Defense series. The direct modern equivalent is a Power Defense Frame 2 (PDG2) breaker, such as the PDG23F0225TFFL, which shares the same footprint and panelboard compatibility.
Which panelboards accept the FDB3225 breaker?
This F-frame breaker is designed for installation in Eaton Series C panelboards, specifically Pow-R-Line 3A (PRL3A) and Pow-R-Line 4 (PRL4) models, as well as compatible motor control centers and switchboards.
Can the FDB3225 be used in reverse-feed applications?
Yes. Standard Eaton thermal-magnetic breakers without dedicated line and load markings, including the FDB3225, are suitable for reverse-feed applications. A retaining bracket must be installed when back-feeding a panelboard to comply with NEC requirements.
Are the standard lugs on the FDB3225 removable?
Yes, the factory-installed mechanical lugs can be removed. This allows the breaker to be fitted with alternate lug kits, multi-wire terminals, or bus connections depending on the specific enclosure requirements.
Can this 3-pole breaker be used in a single-phase system?
Yes. A 3-pole Eaton F-frame breaker can be applied in a single-phase system by wiring the two outer poles. The interruption rating remains valid based on the number of poles breaking the ungrounded legs of the power supply.
How should the thermal-magnetic trip unit be tested?
Testing should be performed using primary current injection in accordance with NETA maintenance testing specifications to verify the fixed long-time and instantaneous trip functions.
