Why Choose the ABB S201M-K0.5 Miniature Circuit Breaker?
The ABB S201M-K0.5 is a high performance single-pole miniature circuit breaker (MCB) designed to provide dependable protection against overloads and short circuits in commercial, industrial and OEM electrical installations. Part of the proven ABB System pro M compact S200M series, this compact device delivers reliable circuit protection together with a high short-circuit breaking capacity.
The S200M range combines thermal overload protection with rapid electromagnetic short-circuit tripping. Featuring a K curve characteristic, the S201M-K0.5 is specifically intended for circuits with moderate to high inrush currents, making it suitable for inductive loads, transformers, control equipment and industrial applications where standard B or C curves may not be appropriate.
With a rated current of 0.5 A, a 230 / 400 V AC rated operational voltage and a 15 kA short-circuit breaking capacity, the S201M-K0.5 provides excellent protection for sensitive low-current circuits while maintaining the robustness expected from the ABB S200M range.
