Autonics SRH3-1475 Three-Phase Solid State Relay, Panel Mount SSR

The Autonics SRH3-1475 is a three-phase solid state relay with an integrated heatsink, designed for reliable switching of AC loads in industrial control systems. It supports 4–30 VDC input control, 48–480 VAC load voltage, and a 75 A rated load current. Its zero-cross turn-on function helps reduce electrical noise and switching stress, making it suitable for heaters, motors, industrial machinery, and other three-phase load applications.
