The ABB S201‑C6 is a compact, single‑pole miniature circuit breaker (MCB) from ABB’s System Pro M Compact S200 series. It is designed for reliable overload and short‑circuit protection in residential, commercial, and light industrial electrical distribution systems. The breaker features a C‑curve thermal‑magnetic trip characteristic, making it suitable for protecting circuits with moderate inrush currents such as lighting, small motors, and general branch circuits. It mounts easily on a standard DIN rail and provides clear ON/OFF status indication with a compact toggling actuator. The device is built to fit in space‑limited panels while delivering robust performance and compliance with modern safety standards.
