CH120AF - 20Amp Circuit Breaker Description
CH120AF - 20Amp Circuit Breaker
If you're replacing an existing CH120AF breaker, chances are you're looking for more than a matching amp rating. The breaker type, mounting style, and panel compatibility all play a role in making sure the replacement fits the equipment it was designed for. The CH120AF is a 20 Amp, 1-pole Type CHAF circuit breaker with a plug-on design and Branch Feeder Type Arc Fault Circuit Interruption (AFCI), intended for use in compatible CH load centers and panelboards.
This breaker is commonly found in residential electrical systems where Branch Feeder AFCI protection is part of the original installation. In addition to helping protect branch circuits from overloads and short circuits, it is designed to detect specified arc fault conditions within the circuit. With a 10kA interrupting rating at 120VAC, the CH120AF is suited for applications that require this particular combination of ratings and protection features.
For electricians and maintenance professionals, finding the right replacement often comes down to matching what's already in the panel. The CH120AF provides the form, fit, and function needed for compatible CH equipment, helping maintain the original configuration of the electrical system. Built to last, it remains a practical choice for repairs, maintenance work, and replacement projects involving existing CH installations.
