CHFCAF120 - 20Amp Circuit Breaker

CHFCAF120 - 20Amp Circuit Breaker

The Eaton CHFCAF120 is a 20 Amp single-pole Combination AFCI circuit breaker designed for use in compatible Eaton Type CH loadcenters. It's commonly used on residential branch circuits where arc fault protection is required and is often installed when replacing an existing CH-series AFCI breaker or maintaining an Eaton CH panel.

Unlike a standard circuit breaker, the CHFCAF120 is designed to detect certain types of arc faults that can occur from damaged wiring, loose electrical connections, worn insulation, or deteriorated conductors. When an arc fault is detected, the breaker interrupts power to the circuit. It also provides traditional thermal-magnetic protection against overloads and short circuits.

With a 20-amp rating, 120/240V capability, and a 10 kAIC interrupt rating, this breaker is commonly used on receptacle circuits, lighting circuits, bedrooms, living areas, home offices, hallways, and other residential branch circuits where AFCI protection may be required by code.

Whether you're replacing a failed breaker, matching an existing panel configuration, or completing routine electrical maintenance, the CHFCAF120 provides the proper fit for approved Eaton CH loadcenters and is built to last.
