The ABB S202-K6 is a two-pole miniature circuit breaker (MCB) from the industry-standard S200 series, featuring a specialized "K" characteristic trip curve. This device is a compact, two-module MCB with a rated current of 6 Amperes. Its defining feature is its "K" curve, which is engineered to provide optimal protection for circuits supplying loads with high inrush currents, such as transformers, solenoids, switching power supplies (SMPS), and certain types of discharge lighting (e.g., LED drivers). The K curve offers a higher magnetic trip threshold than the standard C curve, allowing it to withstand the brief but significant initial surge of current without nuisance tripping, while still providing fast and reliable protection against sustained overloads and short-circuits.
