Challenger A115RN-U Circuit Breaker

Challenger A115RN-U is a 1-pole, 15-amp, 120-volt circuit breaker from Challenger’s A-series, designed to protect a single branch circuit in compatible Challenger panels. As a Type A breaker, it shares the standard form factor used in residential distribution equipment and delivers a 10,000-amp interrupting capacity at 120V (10 kAIC), providing overcurrent protection for common loads in homes and light commercial settings. This model is intended as a replacement for Challenger A-series installations that accept single-pole Type A devices, with mounting designed for easy insertion into panels that support Challenger A-family devices. Typical applications include lighting circuits, receptacle circuits, and other standard 120V branch circuits within panels that specify A-series Type A breakers. When replacing, verify that your panel accepts Challenger Type A breakers and that the replacement matches the original pole configuration and electrical rating (1-pole, 15A, 120V). The A115RN-U designation identifies this particular variant within the Challenger A-series lineup.
