The ABB SB203M I-C1 NA is a four-pole miniature circuit breaker configured for three-phase-plus-neutral electrical systems. It is designed to protect compatible circuits against overloads and short circuits using a thermal-magnetic tripping mechanism.

Part of ABB's System pro M SB200M Industrial range, this device has a rated current of 1 A and a C-type tripping characteristic. It is suitable for low-current industrial control circuits and electrical distribution applications where a neutral pole is required. The breaker supports DIN-rail mounting and has a rated short-circuit breaking capacity of 10 kA.
