A120R - 20 Amp Circuit Breaker

A120R - 20 Amp Circuit Breaker

The circuit breaker is a practical choice for protecting residential and light commercial electrical systems and keeping them running smoothly. Designed as a thin Type A plug-in breaker, it provides dependable 20-amp circuit protection without taking up unnecessary space in the panel. That slim profile can make a real difference when you’re working in tighter load centers or trying to maximize available breaker positions.

Designed with a thermal magnetic trip system, the A120R helps protect circuits from overloads and short circuits before they become larger electrical problems. Its molded case construction is designed for everyday reliability, while the plug-in style makes installation and replacement easier for electricians and maintenance professionals.

With a 10k A.I.C. rating of 120, your breaker is well-suited for common branch-circuit applications involving lighting, receptacles, and general electrical distribution. Whether you're replacing an older breaker or upgrading a panel, the A120R delivers the dependable protection needed for daily operation.
