The Eaton CHFN120A1CS dual-function GFCI AFCI circuit breaker is a 20 Amp device (also cataloged as CHFN120DF) that combines ground-fault and arc-fault protection in a single breaker. The 20 Amp rating defines the maximum current for the protected circuit, and the dual-function design ensures the unit interrupts power under both ground-fault and arc-fault conditions. This model is identified by the CHFN120A1CS and CHFN120DF part numbers, making it easy to reference in Eaton's CHFN family of circuit breakers. Use of this device provides enhanced protection for branch circuits requiring simultaneous GFCI and AFCI capabilities.
