ABB ST203M-D50 Mini Circuit Breaker 480VAC

The System pro M compact ST200M miniature circuit breakers have two different tripping mechanisms, the lingered thermal tripping mechanism for overload protection and the electro mechanic tripping mechanism for short circuit protection. They are accessible in different characteristics (B,C,D,K,Z), configurations (1P,1P+N,2P,3P,3P+N,4P), breaking abilities (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 and CSA 22.2 No. 235, allowing the use for residential, commercial and industrial applications. Bottom-fitting auxiliary contact can be mounted on S200 to save 50% space.
