The ABB S203M-C3 is a 3-pole miniature circuit breaker rated at 3 A with a C-trip curve, designed for DIN-rail mounting in distribution boards and control panels. The C-curve characteristic means it trips between 5 and 10 times rated current — suited for protecting circuits with moderate inrush, such as lighting banks, small motor starters, or general-purpose loads where the startup surge is higher than a resistive load but not extreme.
