The ABB SH30-B40 is a 3-pole miniature circuit breaker from the System pro M compact SH200 range. It features Type B tripping characteristic (trips at 3-5× In — suitable for resistive loads and generator protection). With a rated current of 40A and breaking capacity of 6 kA, this MCB provides reliable overload and short-circuit protection for residential, commercial, and industrial electrical installations. The current-limiting design ensures fast breaking time (2.3–2.5 ms) and Class 3 energy limitation for maximum safety.
