S203-C3 Miniature Circuit Breaker by ABB
System pro M compact S200 miniature circuit breakers are current limiting devices featuring two tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanic mechanism for short circuit protection. They are offered in various characteristics (B,C,D,K,Z), configurations (1P,1P+N,2P,3P,3P+N,4P), with breaking capacities up to 6 kA at 230/400 V AC and rated currents up to 63 A. These breakers comply with IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 standards, suitable for residential, commercial, and industrial use. Bottom-fitting auxiliary contact modules are available to save 50% installation space.
