The ABB SB202-C4DC is a double-pole, 4 A miniature circuit breaker (MCB) from the System pro M compact SB200 DC series. It is designed to protect and control compatible DC electrical circuits against overloads and short circuits. The breaker incorporates a delayed thermal tripping mechanism for overload protection and an electromechanical tripping mechanism for short-circuit protection. Its C-type tripping characteristic is suitable for compatible resistive and inductive loads with low inrush current. With a rated operational voltage of 500 V and a rated short-circuit capacity of 6 kA, it is intended for suitable residential, commercial and industrial electrical installations. The device supports DIN-rail mounting and complies with IS/IEC 60947-2. DC polarity, voltage limits and application-specific breaking capacity must be verified against the manufacturer's installation instructions.
