S203-C20 Miniature Circuit Breaker
Manufacturer: ABB
Type: S200 – 3P – 20 A – C – (AC) 6 kA
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 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 63 A). They comply with IEC/EN 60898-1, IEC/EN 60947-2, UL1077 allowing uses in residential, commercial and industrial applications. Bottom-fitting auxiliary contact can be mounted to save 50% space.
