The device is coil-operated with a 24 V alternating-current control voltage (50\/60 Hz) and wired via screw terminals, conforming to DIN EN 50011 and EN 50 011 standards for control-relay applications. Designed for industrial automation control panels, it serves to interlock signals or pilot other equipment and contactors, enabling safe sequencing and logic in low-power control circuits. As a Siemens 3TH-series auxiliary relay, it integrates smoothly with compatible Siemens relays and contactors to build compact control architectures, reduce wiring complexity, and improve panel organization. Its 24 V AC coil and 2C\/O + 2C\/N configuration support common control schemes such as start-stop interlocks, signal conditioning, and auxiliary feedback in motor control and automation networks. \u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268171714794,"sku":null,"price":0.0,"currency_code":"USD","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0716\/8039\/3450\/files\/GTG-STOCK-017.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-3th2022-0ac2-three-phase-ac-contactor","provider":"GTG Hardware","version":"1.0","type":"link"}
