ABB S203P-K50
System pro M Compact S203P Miniature Circuit Breaker - 3P - K - 50 A
Product Description
The System pro M compact S200P miniature circuit breakers are designed for current limiting and protection against overloads and short circuits. They feature two distinct tripping mechanisms: a delayed thermal mechanism for overload protection and an electromechanical mechanism for short-circuit protection. These breakers come in various characteristics (B, C, D, K, Z), configurations (1P, 2P, 3P, 4P), breaking capacities (up to 25 kA at 230/400 V AC), and rated currents (up to 63 A). All S200P models comply with IEC/EN 60898-1, IEC/EN 60947-2, UL1077, and CSA 22.2 No. 235 standards, making them suitable for residential, commercial, and industrial applications.
The S203P-K50 Miniature Circuit Breaker specifically is a 3P - K - 50 A model that offers efficient protection against overloads and short circuits. Its bottom-fitting auxiliary contact allows for space optimization by saving up to 50% of the space required for conventional circuit breakers.
