The ABB SB203M I-D63 is a three-pole, 63 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 properly designed electrical circuits with high inrush currents, including certain motor and transformer applications. This device belongs to ABB's SB200M Industrial series and is intended for use in industrial and commercial electrical distribution panels. Appropriate selection requires consideration of operating voltage, prospective short-circuit current, cable capacity, and coordination with other protective devices.
