System pro M compact S200M 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 10 kA at 230/400 V AC) and rated currents (up to 63A). All MCBs of the product range S200M comply with IEC/EN 60898-1 and IEC/EN 609 47-2,allowing the use for residential,commercial and industrial applications. Bottom-fitting auxiliary contact can be mounted on S200M to save 50% space.
