CH120AF - 20Amp Circuit Breaker

CH120AF - 20 Amp Circuit Breaker

The CH120AF circuit breaker is a 20 amp, single-pole, plug-on style breaker designed with Branch Feeder Type Arc Fault Circuit Interruption (AFCI) to help protect residential electrical systems from arc-related fire hazards. Built on the CHAF frame, this breaker provides form, fit, and functional replacement compatibility for panels designed to accept CH series devices. With a 10k A.I.C. rating at 120VAC, it is engineered for dependable circuit protection in 120-volt branch circuits. Compact in design and weighing approximately 0.75 lbs with a height of 4.63 inches, the CH120AF installs easily in compatible load centers and is built to last in demanding everyday applications.

Designed for code-compliant residential protection, this breaker helps detect potentially dangerous arc faults while also providing standard overcurrent protection. Its plug-on configuration supports straightforward installation in approved panels, making it a practical solution for maintaining or servicing existing electrical systems.
