The ABB SB204M I-D25 is a four-pole miniature circuit breaker designed to provide overload and short-circuit protection in low-voltage electrical installations. With a rated current of 25 A and a D-type tripping characteristic, it is suitable for compatible circuits that experience high startup or inrush currents. Its thermal tripping mechanism provides overload protection, while its electromagnetic mechanism responds to short-circuit faults. The breaker is part of ABB's SB200-I industrial range and is designed for installation in compatible electrical distribution assemblies. Correct selection requires consideration of the system voltage, prospective short-circuit current, cable capacity and coordination with upstream and downstream protective devices.
