It covers a current rating range of 5.5–8.0 A and is Class 10 rated, providing reliable protection against overload conditions. The device uses screw-terminal connections on both the main circuit and the auxiliary circuit and supports a manual-automatic-reset mode with a trip indicator to show when protection has actuated. It includes phase failure detection (Yes) and does not provide ground fault detection (No). Electrical insulation is rated for 690 V, with a surge resistance of 6 kV, and the unit carries an IP20 front-protection rating. Ambient operating temperature is -40 to 70°C, and typical total power loss is about 6 W. An auxiliary switch is included, and the assembly is intended for mounting onto the corresponding 3RU2 contactor frame for compact motor-protection configurations.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268125053162,"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-3ru2126-1hb0-overload-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
