ABB SB203M-D40 is a three-pole, current-limiting miniature circuit breaker designed to protect low-voltage electrical circuits against overloads and short circuits. It uses a delayed thermal tripping mechanism for overload protection and an electromagnetic tripping mechanism for short-circuit protection. This model has a rated current of 40 A, a D-type tripping characteristic suitable for circuits with high inrush currents, and a rated short-circuit breaking capacity of 10 kA. It belongs to the ABB System pro M compact SB200M range and complies with IS/IEC 60898-1 for residential, commercial and industrial applications.
