Description
Built for residential and commercial safety, the BRN120GF delivers 20A of ground-fault protection to meet strict NEC standards for wet locations. It installs into Eaton Type BR load centers and replaces the legacy GFTCB120 breaker. The unit includes a pigtail neutral and utilizes a short-body footprint to leave more room for wiring in the panel. A built-in self-test function and a visual trip-to-center handle provide immediate feedback during maintenance and troubleshooting.Specifications

Product FAQs
7 answersWhich load centers are compatible with the BRN120GF?
It is designed for Eaton Type BR load centers [1.2.3]. It also serves as a recognized replacement for legacy Bryant, Westinghouse, and Challenger panels that accept Type BR breakers.
Can this breaker replace older Cutler-Hammer GFCB models?
Yes, this is the current direct manufacturer replacement for the discontinued Cutler-Hammer and Eaton GFCB120 and GFTCB120 circuit breakers.
How is the neutral connected on this breaker?
The coiled white pigtail wire must be terminated directly to the neutral bus bar in the panel. The load neutral wire from the branch circuit connects to the designated load neutral lug on the breaker itself.
What is the ground fault trip sensitivity?
This model provides Class A personnel protection, utilizing a standard 5 mA ground fault trip threshold.
Does this unit provide diagnostic trip codes?
Yes, it features an integrated LED diagnostic system. The LED flashes specific codes after a fault, allowing you to determine if the trip was caused by a thermal overload, a short circuit, or a ground fault.
Can this pigtail breaker be installed in a plug-on neutral panel?
Yes. While the pigtail design is intended for standard panels without a plug-on neutral rail, it can safely be installed in a plug-on neutral panel by manually terminating the pigtail to the neutral bus.
How does the breaker handle indicate a tripped state?
It features a trip-to-center mechanism. When a fault occurs, the handle snaps to a middle position between ON and OFF. It must be pushed firmly to the fully OFF position before it can be reset.
