Miniature Circuit Breaker S 200 M UC

The S 200 M UC is ABB’s MCB for DC and AC applications. It impresses with its performance range and the accordingly large amount of approvals

The S200 M UC Z range of miniature circuit-breakers features permanent magnets on the internal arcing chutes able to extinguish an electric arc of up to 500 V DC with Icu = 4.5 kA. However, use of these components establishes circuit-breaker polarity, thus they must be powered in a certain direction. A diagram showing how the string and inverter must be connected is given alongside.
