It is intended for use with Siemens 3RT contactors in sizes S10 and S12 and can be mounted directly on a compatible contactor or installed as a standalone unit; the main circuit connections use busbar terminals and the auxiliary circuit terminates at screw terminals, providing clean, compact wiring in control panels. The device incorporates one normally open and one normally closed auxiliary contact for signaling or interlocking purposes, and supports manual, automatic, and reset operation so technicians can tailor protection behavior to the application and maintenance practices. As part of the Siemens 3RB2 family, it provides integrated overload protection for motor circuits, helping reduce the risk of motor damage and nuisance trips within industrial automation installations that deploy 3RT Sirius starters.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"New","offer_id":46268089893098,"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-3rb2066-1gc2-industrial-control-relay","provider":"GTG Hardware","version":"1.0","type":"link"}
