The ABB SB204M I-D50 is a four-pole industrial miniature circuit breaker designed to provide overload and short-circuit protection in low-voltage electrical distribution systems. It has a rated current of 50 A and a D-type tripping characteristic, intended for compatible applications with high short-duration inrush currents. The device uses thermal protection for overloads and electromagnetic tripping for short circuits. It is part of ABB's System pro M compact range and is designed for installation in compatible electrical distribution assemblies. Selection should take into account operating voltage, prospective fault current, cable capacity and coordination with other protective devices.
