Why Choose the ABB S201M-K3NA Miniature Circuit Breaker?
The ABB S201M-K3NA is a premium miniature circuit breaker (MCB) designed to provide dependable overload and short-circuit protection for demanding electrical installations. As part of the ABB System pro M compact S200M series, it is engineered for residential, commercial and industrial applications where high inrush currents are present, making it particularly suitable for motors, transformers and inductive loads.
The K tripping characteristic allows the breaker to tolerate higher starting currents while maintaining effective protection against overloads and faults. Its current-limiting design helps reduce the effects of fault energy, protecting both equipment and wiring from unnecessary damage.
With a rated current of 3 A and a 1P+N configuration, the S201M-K3NA provides compact and reliable protection for motor control circuits, industrial machinery, automation systems and OEM equipment. Its DIN rail mounting format enables quick installation into modern electrical panels and distribution boards.
