ABB S201-K10A Miniature Circuit Breaker 230-400V

ABB S201-K10A is a 1-pole miniature circuit breaker from ABB’s System pro M compact (S200) family, designed to protect a single-phase circuit on 230/400 V AC systems. It carries a nominal current rating of 10 A and uses a K-type trip characteristic, which responds to fault currents with a faster release for moderate inrush conditions. The S201-K10A designation identifies the 1-pole, K-curve variant within the S201 family, making it suitable for branch circuits such as lighting and other small-power feeders in residential or light-commercial electrical installations. As part of ABB’s widely deployed protection lineup, this model provides overload and short-circuit protection within ABB’s low-voltage distribution range, aligning with standard European wiring practices for single-phase circuits.
