System Pro M compact S200 miniature circuit breakers are current-limiting. They have two different tripping mechanisms: the delayed thermal tripping mechanism for overload protection and the electromechanic tripping mechanism for short circuit protection. They are available in different characteristics (B,C,D,K,Z), configurations (1P,1P+N,2P,3P,3P+N,4P), breaking capacities (up to 6 kA at 230/400 V AC), and rated currents (up to 63A). All MCBs in the product range S200 comply with IEC/EN 60898-1, IEC/EN 60947-2, and UL1077, allowing their use for residential, commercial, and industrial applications. Bottom-fitting auxiliary contacts can be mounted on the S200 to save 50% space.
