The ABB SB204M I-D2 is a four-pole miniature circuit breaker designed to protect electrical circuits against overloads and short circuits. It has a rated current of 2 A and a D-type tripping characteristic, making it suitable for compatible industrial applications where equipment may draw high inrush currents during startup. Its thermal tripping mechanism provides overload protection, while its electromagnetic mechanism provides short-circuit protection. The breaker is designed for installation in compatible low-voltage distribution systems. Selection should take into account the system voltage, prospective short-circuit current, conductor ratings and coordination with other protective devices.
