Eaton Cutler-Hammer CH120CAF Arc Fault Breaker

Eaton Cutler-Hammer CH120CAF Arc Fault Breaker is a 1-pole, 20-amp device designed for 120-volt circuits that plugs into a compatible panel as a plug-on branch feeder. The CH120CAF designation places it in Eaton’s Cutler-Hammer CH series and identifies it as arc-fault protection (CAF). This single-pole breaker is rated for 20A on a 120V circuit, making it suitable for protecting a single branch circuit in an appropriate electrical panel. As a plug-on branch feeder, it installs by snapping onto the panel’s bus in compatible Eaton/Cutler-Hammer panels, providing arc-fault protection without the need for separate mounting hardware beyond the standard conductors of the circuit. Its 120-volt, 20-amp, 1P configuration corresponds to common 120V branch circuits used in panel installations.
