The ABB SB204M I-D63 is a four-pole miniature circuit breaker designed to provide overload and short-circuit protection in low-voltage electrical distribution systems. With a rated current of 63 A and a D-type tripping characteristic, it is suitable for compatible circuits that experience high short-duration inrush currents. The breaker uses a thermal tripping mechanism to protect against overloads and an electromagnetic mechanism to respond to short circuits. It belongs to ABB's System pro M compact SB200-I range and is intended for installation in compatible electrical distribution assemblies. Correct selection requires verification of the system voltage, prospective fault current, conductor capacity and coordination with other protective devices.
