The ABB SB203M I-C1.6 NA is a four-pole miniature circuit breaker designed for three-phase electrical systems with a neutral conductor. It protects compatible electrical circuits against overloads and short circuits through a thermal-magnetic tripping mechanism.

Part of ABB's System pro M SB200M Industrial range, this device has a rated current of 1.6 A and a C-type tripping characteristic. It is suitable for low-current industrial control circuits and electrical distribution applications that require a three-phase-plus-neutral configuration. The breaker supports DIN-rail mounting and has a rated short-circuit capacity of 10 kA.
