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 VAC) and rated currents (up to 63 A). All MCBs of the product range S200 comply with IEC/EN 60898-1, IEC/En 60947-2, UL 1077 and CSA 22.2 No. 235. Bottom-fitting auxiliary contact can be mounted on S200 to save 50% space.
