The ABB S201‑C1 is a single‑pole miniature circuit breaker (MCB) from ABB’s System pro M compact S200 series. It provides overload and short‑circuit protection for electrical circuits in residential, commercial, and industrial applications. The breaker uses a Type C thermal‑magnetic trip characteristic, making it suitable for circuits with moderate inrush currents such as small motors, lighting, and general branch circuits. It is designed for DIN‑rail mounting and features a compact, finger‑safe structure and clear ON/OFF status indication. The breaker can accept accessories like auxiliary contacts or shunt trips for extended functionality.
