ABB 2CDS253001R0321

The S203-D32 Miniature Circuit Breaker is a compact solution designed to provide reliable protection against electrical faults. This device features two distinct tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short circuit protection. The breaker is available in multiple characteristics (B, C, D, K, Z), configurations (1P, 2P, 3P, 4P), breaking capacities (up to 6 kA at 230/400 V AC) and rated currents (up to 63A). All models comply with IEC/EN 60898-1, IEC/EN 60947-2, UL1077 standards, making them suitable for residential, commercial, and industrial applications. The bottom-fitting auxiliary contact allows for space optimization by saving up to 50% of the space required.
