This 3RS1800‑series device provides a 24 V universal coil (AC\/DC) or a 110–120 V AC coil variant, allowing flexible integration with both low‑ and high‑voltage control circuits. Rated for up to 3 A on its output contacts at up to 250 VAC (AC‑15) at 50\/60 Hz, it uses three SPDT contact sets for independent switching. Typically used as a phase\/voltage loss relay to detect a missing phase and trigger protective actions in industrial drives, motor controllers, and control panels.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268102377706,"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-3rs18001hq00-electromechanical-relay-with-three-changeover-contacts","provider":"GTG Hardware","version":"1.0","type":"link"}
