Product FAQs
7 answersCan the BRN125GF replace older Cutler-Hammer GFCI breakers?
Yes, the BRN125GF is the direct replacement for older 25A single-pole GFCI models, including the GFTCB125 and GFCB125. It fits the same Type BR load centers but features an updated short-body design.
What load centers are compatible with this 25A GFCI breaker?
This breaker is designed exclusively for Eaton and Cutler-Hammer Type BR load centers. It is not compatible with Type CH panels or load centers from other manufacturers.
Can I install this pigtail neutral breaker in a Plug-On Neutral panel?
Yes. While it features a pigtail neutral wire, it can be installed in both standard and Plug-On Neutral Type BR load centers by connecting the pigtail directly to the neutral bus bar.
What level of ground fault protection does the BRN125GF provide?
It provides Class A ground fault protection, meaning it is designed to trip when it detects a ground fault current of 5mA. This level of protection is required for personnel safety in wet or damp locations.
Does this breaker include a self-test feature?
Yes, the BRN series includes built-in self-test functionality to periodically verify the GFCI circuitry is working correctly. It also features an integrated LED trip indicator to help diagnose faults.
How does the short-body design of the BRN series benefit installation?
The compact footprint of the BRN series takes up less space in the load center gutter, providing more room for wire routing and making it easier to terminate the connections.
What wire sizes are accepted by the box lugs on this breaker?
The terminals accept 14 AWG to 4 AWG copper or aluminum wire. Always ensure the wire size is appropriate for the 25A circuit rating and torque the lugs to the manufacturer specifications.
