Why Choose the ABB S201M-K2NA Miniature Circuit Breaker?
The ABB S201M-K2NA is a compact and reliable 1P+N miniature circuit breaker (MCB) from the trusted ABB System pro M compact S200M series. Designed to provide dependable overload and short circuit protection, this 2 A Type K MCB with switched neutral is ideal for control, auxiliary and industrial electrical circuits where reliable protection and neutral isolation are required.
The S201M-K2NA combines ABB's current limiting technology with delayed thermal overload protection and electromechanical short circuit protection. This helps reduce let-through energy during fault conditions while protecting cables, equipment and connected electrical systems from overloads and short circuits.
With a 2 A rated current, Type K tripping characteristic, 1 protected pole plus switched neutral and a 10 kA breaking capacity, the ABB S201M-K2NA is well suited to control panels, transformers, relay circuits, auxiliary supplies, automation equipment and installations with moderate to higher inrush currents. Its DIN rail mounting format enables quick installation inside switchboards, distribution boards and industrial enclosures.
