S203M-C50 Miniature Circuit Breaker by ABB
Product ID: 2CDS273001R0504
EAN: 4016779543996
Description: 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. 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 63 A). All comply with IEC/EN 60898-1 and IEC/EN 60947-2, suitable for residential, commercial and industrial applications. Bottom-fitting auxiliary contact can be mounted to save 50% space.
Electrical Specifications: Rated ultimate short-circuit breaking capacity at 230 V AC is 25 kA, at 400 V AC and 440 V AC is 15 kA. Rated service short-circuit breaking capacity at 133 V AC is 15 kA, and at 230 V AC is 7.5 kA. Rated operational voltage per IEC 60898-1 is 400 V AC, IEC 60947-2 is 440 V AC. Rated insulation voltage Ui is 440 V, with rated impulse withstand voltage Uimp of 4 kV (5 kV at 2000 m altitude, 6.2 kV at sea level). Rated current is 50 A.
