Eaton BRHN120AF AFCI Combination Circuit Breaker

Eaton BRHN120AF is a 1-pole, 20-amp AFCI combination circuit breaker (model BRHN120AF). This BR-series device delivers arc-fault protection alongside standard overcurrent protection in a single breaker, helping to mitigate the risk of fires caused by arcing on a branch circuit. As an AFCI combination breaker, it trips when an electrical arc fault is detected and also interrupts the circuit on overload, providing two layers of protection in one compact unit. The part number BRHN120AF identifies the specific 20-amp, single-pole configuration within Eaton's BR family of protection devices. Use of this breaker is appropriate for applications requiring arc-fault protection on individual branch circuits where a 20-amp rating is suitable. By combining arc-fault detection with overcurrent interruption, this breaker provides a compact, integrated solution for protecting branch circuits from two common electrical hazards.
