Eaton CL120CAF AFCI Arc Fault Plug-On Circuit Breaker

The Eaton CL120CAF is a 20A, 1-pole, 120V plug-on circuit breaker with combination arc-fault (AFCI) protection. As a combination AFCI device, it detects arcing faults and interrupts power on the affected circuit, providing arc-fault protection in addition to standard interruption for overcurrent events. The 1-pole design protects a single hot conductor, consistent with 120V branch-circuit configurations. The CL120CAF designation identifies this specific unit within Eaton’s AFCI line, and its plug-on form factor is designed for straightforward installation in appropriate electrical systems. With a 20A rating, this breaker handles circuits drawing up to 20 amperes at 120V, making it suitable for typical 120V loads on smaller branch circuits. The device’s AFCI capability addresses arc-fault conditions by monitoring electrical signatures and interrupting power when a dangerous arc is detected, all within a compact, plug-on package that matches standard breaker form factors. Its 120V operation and 20A rating align with common requirements for small-appliance or lighting circuits that benefit from AFCI protection.
