It handles a main current range of 2.8 to 4.0 A and includes NC and NO auxiliary contacts, with spring-type terminals on both the main and auxiliary circuits for secure wiring. The unit mounts directly to the contactor (contactor mounting) and offers a Manual-Automatic-Reset option to restore operation after an overload. Built for compact control panels, it withstands ambient temperatures from -40 to +70 °C, features front IP20 protection, and delivers 6 kV impulse voltage resistance, with installation altitude up to 2,000 meters and shock resistance of 8 g \/ 11 ms. The device is a member of Siemens’ SIRIUS line and provides three main circuit poles, making it suitable for three-phase motor circuits in small-to-medium automation applications, with typical power loss around 5.4 W. \u003c\/p\u003e\n\u003cp\u003e\u003c\/p\u003e\n\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268124135658,"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-ag-3ru2116-1ec0-thermal-overload-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
