Description
S201-C50 Miniature Circuit Breaker
System pro M compact S200 miniature circuit breakers are current limiting devices. They feature two tripping mechanisms: a delayed thermal tripping mechanism for overload protection and an electromechanic tripping mechanism for short circuit protection. They are available in various 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 63 A. All MCBs in the S200 range comply with IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077, making them suitable for residential, commercial, and industrial applications. A bottom-fitting auxiliary contact can be mounted on the S200 to save 50% space.
