QO120AFI - 20 Amp Circuit Breaker

QO120AFI - 20 Amp Circuit Breaker

The QO120AFI is a 20 Amp, single-pole QO plug-on circuit breaker designed for use in your compatible 120VAC QO load centers and panelboards. Featuring Arc Fault Circuit Interruption (AFCI) technology, this breaker is intended to help you detect certain potentially hazardous arc fault conditions while providing branch circuit overcurrent protection. With a 10kA interrupting rating at 120VAC, it is well-suited for residential and light commercial electrical systems where AFCI protection is required or specified. Its compact plug-on design allows for straightforward installation in compatible equipment, making it a practical form, fit, and functional replacement for existing QO AFCI breakers. Built to last, the QO120AFI is engineered for dependable operation while maintaining compatibility with the electrical system it was designed to serve.
