The ABB SB204M I-D16 is a four-pole industrial miniature circuit breaker designed to protect low-voltage electrical circuits against overloads and short circuits. It has a rated current of 16 A and a D-type tripping characteristic, making it suitable for compatible applications with high starting or inrush currents. Its thermal and electromagnetic trip mechanisms provide protection against sustained overloads and short-circuit faults. The breaker is part of ABB's SB200-I industrial range and is designed for use in compatible electrical distribution assemblies. Proper selection requires checking the rated operating voltage, prospective short-circuit current, conductor capacity and coordination with other protective devices.
