ABB R100.30-IO Industrial Semiconductor Contactor

ABB R100.30-IO is a semiconductor contactor in ABB’s R100 family that provides solid-state switching for industrial loads in automation systems. It takes a DC control signal in the 4–32 V range and switches main-load currents up to 30 A (Ie) without the wear associated with mechanical contacts. The module carries ABB order number 1SAR113030R8607 and weighs approximately 0.25 kg (0.55 lb), making it compact enough for panel mounting and integration with standard control wiring. As part of the R100 line, the R100.30-IO sits alongside variants such as R100.20, R100.30-ZS, and R100.45, which differ in current ratings and configurations to fit diverse motor control and automation applications. This device is suitable for controlling motors, pumps, fans, and other inductive or resistive loads in automation systems where a solid-state switch provides reliable on/off control activated by a low-voltage DC signal.
