It features spring-loaded terminals for easy wiring and a front-connection design compatible with SIRIUS assemblies; the unit is typically used to signal or interlock in motor-control circuits. The auxiliary block carries a NO path that leads and an NC path that lags in the switch sequence, and it supports switching voltages up to 690 VAC and 250 VDC, making it suitable for a range of control-signal applications in industrial panels. This 11U-block is part of the SIRIUS Innovations line and is intended to accompany 3RT2\/3RH2 equipment to provide two extra auxiliary contacts in a single compact block.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"New","offer_id":46268096741610,"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-3rh2911-2fb11-auxiliary-contact-switch-block","provider":"GTG Hardware","version":"1.0","type":"link"}
