Product FAQs
9 answersWhat wire sizes and materials are compatible with the lugs on this breaker?
The standard lugs accept both aluminum and copper conductors ranging from 4 AWG to 4/0 AWG. Ensure you apply the correct torque specifications as outlined on the breaker faceplate during installation.
Which enclosures and panels are compatible with the PDG23M0125TFFJ?
This Power Defense Frame 2 breaker is designed for use in Eaton Power Defense enclosures, as well as compatible Eaton panelboards and switchboards that accept Frame 2 panel-mount breakers.
Can the trip settings on this Frame 2 breaker be adjusted in the field?
No. This specific model features a fixed thermal and fixed magnetic trip unit. The long-time and instantaneous protection settings are factory-set and cannot be modified.
Is this breaker suitable for high fault current applications at 480V?
Yes, it provides a 65kA interrupting capacity at 480VAC, making it suitable for many commercial and industrial systems requiring robust fault protection. It also carries a 100kA rating at 240VAC.
How is this breaker mounted within a panelboard?
It utilizes a standard panel mount configuration. It bolts directly to the chassis or mounting pan of compatible Eaton switchboards and panelboards.
Can this molded case circuit breaker be used in direct current systems?
Yes, it is rated for use in DC applications up to 250VDC with an interrupting capacity of 22kA. Verify your specific wiring configuration meets Eaton guidelines for DC switching.
Does the Power Defense series replace older Eaton Cutler-Hammer lines?
The Power Defense series is Eaton's modern global breaker platform. While it serves similar applications as the legacy Series C F-Frame breakers, verify physical dimensions and mounting hardware requirements before using it as a direct drop-in replacement.
Does this breaker come with line and load terminals installed?
Yes, it is configured as a feed-thru breaker and includes standard lugs on both the line and load sides for immediate wire termination.
What maintenance is required for the thermal magnetic trip unit?
Thermal magnetic trip units are sealed and require no internal maintenance. Routine visual inspections, verifying lug torque, and exercising the breaker mechanism periodically are recommended to ensure reliable operation.
