ABB S201-K20

ABB’s System pro M compact S200 miniature circuit breakers are engineered for efficient current limiting and reliable circuit protection. Each breaker integrates two separate tripping mechanisms: a thermal delay for detecting overloads and an electromechanical trip for rapid short-circuit response.

These MCBs are offered in a range of tripping curves (B, C, D, K, Z), multiple pole configurations (1P, 1P+N, 2P, 3P, 3P+N, 4P), and support breaking capacities up to 6 kA at 230/400 V AC. The series covers rated currents up to 63 A, making them suitable for diverse environments—from residential buildings to commercial facilities and industrial setups.

The S200 line complies with major international standards, including IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077, ensuring compatibility and safety across global applications.

For space-saving installations, optional bottom-mounted auxiliary contacts can be added, reducing total width by up to 50%. The S200 range delivers compact, flexible, and robust protection for modern electrical systems.
