The coil accepts a control voltage range of 21–33 V for AC or DC operation and includes an integrated varistor to suppress spike voltages, with a single normally closed auxiliary contact to support basic monitoring and interlock functions. Mounting on TH 35 rails in size S2 is supported, with screw-terminal connections and the option for snap-on mounting, enabling flexible installation in compact control panels. In typical industrial automation use, this contactor handles three-phase motors in conveyors, pumps, and fans, providing robust switching performance, straightforward PLC interfacing, and a space-efficient footprint.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268120727786,"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-3rt2037-1sb30-three-phase-ac-contactor","provider":"GTG Hardware","version":"1.0","type":"link"}
