Product FAQs

6 answers
What equipment is the PDG13G0125TFFJ designed to fit?

This breaker is engineered for installation in Eaton Power Defense panelboards, switchboards, and standalone enclosures. As part of Eaton's globally rated Power Defense series, it serves as the modern upgrade path for legacy Series G (EG-Frame) and Series C (F-Frame) installations.

What does the TFFJ suffix indicate in the catalog number?

The suffix specifies the trip unit and terminal configuration. The T stands for a thermal-magnetic trip unit, the FF indicates that both the thermal and magnetic trip settings are fixed, and the J denotes standard box lug terminals on both the line and load sides.

What does the G represent in the PDG13G prefix?

The first G indicates it is a globally rated Power Defense breaker, meaning it meets UL, CSA, IEC, and CCC standards. The second G designates the specific interrupting rating tier, which for Frame 1 corresponds to the 35kA at 480VAC performance level.

Can this breaker be reverse fed?

Yes. Because it utilizes a standard fixed thermal-magnetic trip unit without electronic communication modules or specific line/load directional requirements, this breaker can be safely reverse fed if required by your panel layout.

How is this breaker mounted on a DIN rail?

While the breaker supports DIN rail mounting, it does not snap directly onto a standard rail out of the box. You will need to install the appropriate Eaton Power Defense Frame 1 DIN rail adapter kit to secure the breaker properly to the rail.

How should this three-pole breaker be wired for DC applications?

While rated for up to 250VDC, applying a multi-pole AC/DC breaker in a direct current circuit typically requires wiring two or three poles in series to safely interrupt the DC arc. You must consult Eaton's Power Defense application guidelines for the correct series wiring diagram based on whether your DC system is grounded or ungrounded.
