It is coil-driven by 24 V DC and wired via screw terminals, and it includes a captive auxiliary switch for straightforward integration in control circuits. The device is rated for up to 690 V AC on its auxiliary contacts and supports a control-current rating (Ie) of 3 A at 400 V, making it suitable for signaling and interlock duties rather than heavy motor loads. With the S00 frame and screw-term connections, it integrates neatly into Siemens SIRIUS control panels and cabinets. Typical applications include signaling, interlocks, PLC inputs, and other control-circuit tasks where a robust, multi-contact auxiliary unit is needed.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"New","offer_id":46268096217322,"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-3rh2271-1bb40-auxiliary-contactor-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
