The ABB SB202-C20DC is a double-pole, 20 A miniature circuit breaker (MCB) from the System pro M compact SB200 DC series. It is designed to protect and control compatible direct-current (DC) electrical circuits against overloads and short circuits. The breaker uses thermal and electromagnetic tripping mechanisms to provide overload and short-circuit protection. Its C-type tripping characteristic is intended for compatible resistive and inductive loads with relatively low inrush current. The double-pole configuration enables simultaneous switching of both poles. Designed for DIN-rail mounting, this circuit breaker is intended for suitable residential, commercial and industrial electrical installations. Its rated voltage, short-circuit breaking capacity and DC polarity requirements must be verified against the manufacturer's technical documentation for the intended installation.
