The ABB SB204M I-D1 is a four-pole miniature circuit breaker designed to provide overcurrent protection and circuit isolation in industrial electrical installations. With a rated current of 1 ampere and a D-type tripping characteristic, it is intended for applications where connected equipment may draw high short-duration inrush currents during startup. The breaker helps protect electrical circuits against overloads and short circuits when installed in a properly designed and coordinated protection system. Its compact modular construction is suitable for installation in compatible electrical distribution assemblies. Verify the rated voltage, breaking capacity, mounting requirements and applicable standards against the official datasheet before selecting it for an installation.
