Product FAQs
6 answersWhat is the difference between the Eaton BRN120AF and the older BR120AF?
The BRN120AF is the direct replacement for the legacy BR120AF and BRCAF120 breakers. It features a newer short-body design that creates more wire-way space in the panel, improved diagnostic LED trip codes for easier troubleshooting, and updated algorithms to reduce nuisance tripping.
Which load centers are compatible with the BRN120AF circuit breaker?
This breaker is designed exclusively for use in Eaton and Cutler-Hammer Type BR load centers that accept 1-inch plug-on breakers. It is not interchangeable with Type CH panels or other manufacturer brands.
Does the BRN120AF use a plug-on neutral or a pigtail neutral connection?
This model features a traditional pigtail neutral. It requires you to manually route and connect the attached white wire to the neutral bus bar in your load center. It is ideal for older panels that do not have plug-on neutral capabilities.
What type of arc fault protection does the BRN120AF provide?
It is a Combination Arc Fault Circuit Interrupter (CAFCI). In addition to standard thermal-magnetic overload and short-circuit protection, it detects both series and parallel arcing faults to mitigate fire hazards in residential branch circuits.
Can the BRN120AF be used on a 240V circuit?
No. This is a single-pole breaker rated strictly for 120VAC applications. It is designed to protect standard 120V, 20-amp branch circuits and cannot be used for 240V loads.
How do I use the diagnostic LED on the BRN120AF?
The breaker includes diagnostic trip codes to assist with troubleshooting. When the breaker trips, the LED will blink in specific patterns to indicate whether the fault was a thermal overload, a short circuit, or an arc fault.
