S204-C25 Miniature Circuit Breaker
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. Available in 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 comply with IEC/EN 60898-1, IEC/EN 60947-2, UL1077 allowing use for residential, commercial, and industrial applications. Bottom-fitting auxiliary contact can be mounted on S200 to save 50% space.
