Product FAQs
8 answersDoes the PDG23G0125TFFL come with line and load lugs?
The "L" suffix in this specific catalog number indicates it includes standard load-side lugs only. The line side is designed to bolt directly to the bus in compatible switchboards or panelboards. Verify your panel connection requirements before installation.
Can this Frame 2 breaker be mounted on a DIN rail?
While the breaker body natively supports bolt-on or panel mounting, it can be easily adapted for DIN rail installations using an official Power Defense Frame 2 DIN rail adapter, such as part number PDG2XDIN75.
Can I use this Power Defense breaker to upgrade an older Series C F-Frame installation?
Yes, the Power Defense Frame 2 (PDG2) series is designed as a direct replacement for legacy Eaton Series C F-Frame and Series G EG-Frame breakers, sharing the same physical footprint for seamless retrofits.
Are the lugs on this breaker interchangeable with legacy Series C F-Frame breakers?
Yes, the Power Defense Frame 2 (PDG2) series is designed to be compatible with legacy Series C F-Frame terminals. You can reuse or swap standard F-Frame lugs and terminals with this modern equivalent.
Is the PDG23G0125TFFL a direct replacement for the obsolete Eaton FD3125?
Yes, this breaker is the modern, drop-in equivalent for the legacy Series C FD3125. It shares the same physical dimensions and provides the identical 35kAIC interrupting capacity at 480VAC.
What does the "TFF" designate in the PDG23G0125TFFL catalog number?
In Eaton's nomenclature, "TFF" indicates a Thermal-Magnetic trip unit with Fixed Thermal and Fixed Magnetic settings. This provides reliable, non-adjustable overcurrent and short-circuit protection.
What is the difference between Eaton's PDG and PDD series circuit breakers?
PDG series breakers (like this unit) are globally rated, carrying UL, CSA, IEC, and CCC certifications for use in systems up to 600VAC. PDD series breakers are domestic, UL-only models limited to 240VAC applications.
Does this breaker feature Arcflash Reduction Maintenance System (ARMS) technology?
No, this specific model is equipped with a basic fixed thermal-magnetic trip unit. ARMS technology is exclusively available on Power Defense circuit breakers equipped with advanced electronic trip units, such as the PXR25.
