The WG A3 series is a panel-mounted solid state relay designed for switching three-phase AC loads up to 45 A and line voltages up to 660 VAC, with DC input control from 3 to 32 V and a maximum control current of 25 mA. It features back-to-back SCRs for zero-cross and random firing, an isolation voltage of 4000 V between input and output, and a maximum operating temperature of +80 °C. The device is housed in a glass-filled polyester case with a nickel-plated aluminium base plate, measuring 107 mm in length and 36 mm in width, and weighs approximately 430 g. Snubber network is 47 Ω / 10 nF, with a turn-on time of up to 11 ms for zero-cross versions and 0.1 ms for random firing. The part is rated for an on-state voltage of 1.6 V peak and off-state dv/dt of 1000 V/μs.
