It delivers adjustable overload protection for three-phase motors in a 20–25 A range with Class 10 trip characteristics, helping prevent overheating from overload or phase imbalances. The unit uses screw-terminal connections for both the main circuit and the auxiliary circuit, supporting robust wiring in industrial panels, and it offers a manual or automatic reset option to control fault recovery after protection trips. Built for standalone installation in motor control gear, this relay guards motors from overload, phase failure, and related thermal stress across all three lines, making it suitable for pumps, fans, compressors, and other common 3-phase applications. \u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268125610218,"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-3ru2126-4db0-thermal-overload-relay-20-25-a","provider":"GTG Hardware","version":"1.0","type":"link"}
