The ABB SB203M I-D10 is a three-pole, 10 A industrial miniature circuit breaker (MCB) designed to protect compatible low-voltage electrical circuits against overloads and short circuits. It features a D-type tripping characteristic, suitable for applications with high inrush currents, such as certain motors, transformers and industrial equipment, when correctly rated for the circuit. Its compact modular construction supports DIN-rail installation in compatible distribution boards, switchboards and industrial control panels.
