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 of the product range S200 comply with IEC/EN 60898-1,IEC/EN 60947-2,UL1077 allowing the use for residential,commercial and industrial applications. Bottom-fitting auxiliary contact can be mounted on S200 to save 50% space.

• Our MCBs are advanced for more than 120 years in the history and mindset of Hugo Stotz.Today we offer feasible MCB solutions for all kind of applications,which are developed in close touch to market requirements from various branches. Numerous patents have been made during this time and ensure our market position as the “original” and innovation leader. Terminal
