Product FAQs
6 answersWhat load centers are compatible with the BRN120A1CS circuit breaker?
This breaker is designed for use in Eaton, Cutler-Hammer, and Bryant Type BR load centers and meter breaker panels that accept 1-inch plug-on breakers.
Does the BRN120A1CS replace any older Eaton breaker models?
Yes, the BRN120A1CS replaces the discontinued BRLAFGF120 dual-function breaker. It is also the retail-packaged equivalent of the BRN120DF catalog number.
Does this breaker require a plug-on neutral panel?
No. The BRN120A1CS features a standard pigtail neutral, meaning it can be installed in traditional Type BR panels that do not have a plug-on neutral bar. The pigtail wire connects directly to the neutral bus of the panel.
What is the advantage of the short-body design on the BRN120A1CS?
The compact footprint of this short-body breaker takes up less physical space in the panel. This leaves more room in the wire-way for easier routing and termination of branch circuit conductors.
What type of protection does a dual-function breaker like the BRN120A1CS provide?
It provides both Arc Fault Circuit Interrupter (AFCI) and Ground Fault Circuit Interrupter (GFCI) protection in a single device. This protects branch circuits against electrical fires caused by arcing and shock hazards caused by ground faults, allowing for a single point of reset.
How does the BRN120A1CS indicate a tripped condition?
This breaker features a trip-to-center handle position and a visual trip indicator, allowing users to quickly identify a tripped circuit in the panel. It also includes a self-test function to ensure the AFCI and GFCI electronics are operating correctly.
