The ABB S203-K16 miniature circuit breaker protects motors, transformers and auxiliary circuits against overloads and short circuits. Its K curve makes it suitable for loads with high starting currents in residential, commercial and industrial installations.
It mounts on a DIN rail and features safety screw terminals with a double chamber, as well as a separate chamber for busbars and cables. Its markings and identifiers are laser-printed, and the screws remain captive in the housing.
