The ABB SB203M I-D32 is a three-pole, 32 A miniature circuit breaker designed to provide overload and short-circuit protection in industrial and commercial electrical distribution systems. It features a D-type tripping characteristic, making it suitable for properly designed circuits with high starting or inrush currents, such as certain motor and transformer applications. The circuit breaker is part of ABB's SB200M Industrial series and is intended for installation in electrical distribution panels. Selection must be based on the system voltage, prospective short-circuit current, cable ratings, and applicable electrical protection requirements.
