The ABB SB204M I-D3 is a four-pole industrial miniature circuit breaker designed to provide overcurrent protection and circuit control in low-voltage electrical installations. Rated at 3 A, it features a D-type tripping characteristic for applications with high short-duration inrush currents. The device provides protection against overloads and short circuits and is intended for use in industrial electrical distribution systems. Its compact modular design allows installation in compatible distribution assemblies. Proper selection requires verification of the operating voltage, rated breaking capacity, conductor sizing and coordination with upstream and downstream protective devices.
