MCBs protect installations against overload and short-circuit, warranting reliability and safety for operations. New System pro M compact S200 series are current limiting overcurrent protective devices. They have two different tripping mechanisms, the delayed thermal tripping mechanism for overload protection and the magnetic 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 25 kA) and rated currents (up to 63A). Depending on the product range, New System pro M compact S200 series comply with

• IEC/EN 60898-1
• IEC/EN 60947-2
• UL 1077
• UL 489
• CSA 22.2 No. 235
• CSA 22.2 No. 5

allowing the use for residential, commercial and industrial applications.
