It covers a 17 to 22 A motor current range, is built in the S0 frame size, and provides IEC Class 10 thermal protection. Designed for contactor mounting, the unit attaches to the main circuit side of a Siemens contactor and uses spring-type terminals for both the main circuit and the auxiliary circuit, with a reset that can be performed manually or automatically. The 3RU2 family is intended for inverse-time delayed protection of loads with normal starting characteristics, guarding motors against overheating due to overload or phase faults. Typical applications include protection of three-phase motors in industrial drives—pumps, fans, conveyors, and processing equipment—where reliable, resettable protection is required in control panels.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268125577450,"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-3ru2126-4cc0-overload-relay-thermal-motor-protection","provider":"GTG Hardware","version":"1.0","type":"link"}
