Eaton Cutler-Hammer CHFAFGF120 20A 1P Circuit Breaker, Type CH, AFCI, GFCI | AmpState

Upgrade your electrical protection with the Eaton Cutler-Hammer CHFAFGF120. This 1-pole, 20-amp circuit breaker from the Type CH family combines AFCI (arc-fault circuit interrupter) and GFCI (ground-fault circuit interrupter) protection in a single, reliable device. Designed for use in panelboards, load centers, and general electrical distribution, it’s an ideal choice for retrofit projects where maintaining a consistent part number is important for maintenance planning.

The CHFAFGF120 delivers dual-layer protection in one compact unit. AFCI protection helps detect dangerous arcing faults that can spark and ignite wiring, while GFCI protection guards against ground faults that could energize exposed surfaces or create shock hazards. Together, they provide robust, code-aligned safety for branch circuits in living spaces, kitchens, bathrooms, basements, garages, and outdoor outlets.
