CUTLER BR3030 NS 30A 120V 1P {AIC}K Circuit Breaker

The CUTLER BR3030 NS 30A 120V 1P circuit breaker is a single-pole protective device designed to interrupt a 120-volt branch circuit when electrical overloads or faults occur, rated for 30 amperes. As part of the BR family—and tracing back to Cutler-Hammer—the NS variant is intended for use in BR-series panels or enclosures in which this form factor is supported. With a 30 A rating at 120 V, it provides overcurrent protection to prevent overheating of conductors and equipment on the protected circuit. Typical applications include safeguarding branch circuits in residential or light commercial electrical panels, where a single hot conductor requires protection and proper return path is maintained. The BR3030 NS designation identifies its place within the BR lineup and ensures compatibility with other BR-series devices in compatible panels and distribution systems.
