The ABB S202-K32 is a two-pole miniature circuit breaker (MCB) from the S200 series, featuring a specialized "K" characteristic trip curve. This device is a compact, two-module MCB with a rated current of 32 Amperes. The defining feature is its "K" curve, which is engineered specifically for the protection of circuits supplying high inrush current loads, such as transformers, solenoid valves, and certain types of discharge lighting (e.g., some LED drivers, power supplies). Compared to standard B, C, or D curves, the K curve provides a higher magnetic trip threshold to tolerate the brief but significant intrush currents without nuisance tripping, while still offering fast protection against sustained overloads and short-circuits.
