The ABB SB203M I-D40 is a three-pole, 40 A industrial miniature circuit breaker designed to provide overload and short-circuit protection in electrical distribution systems. It features a D-type tripping characteristic, suitable for appropriately designed circuits with high inrush currents, including certain motor and transformer applications. This circuit breaker belongs to ABB's SB200M Industrial series and is intended for use in industrial and commercial electrical panels. Correct selection requires consideration of the operating voltage, prospective short-circuit current, cable capacity, and coordination with other protective devices.
