It provides one normally open (NO) and one normally closed (NC) contact, with screw terminals for the auxiliary circuit, and is rated for insulation up to 690 V with a 6 kV surge withstand. The device delivers a mechanical life of up to 10,000,000 switching cycles and an electrical life of about 200,000 cycles at AC-15, 230 V, ensuring long-term reliability in automation panels. Featuring a snap-on front-mount design for quick installation on suitable Siemens assemblies, it is a compact, two-pole auxiliary block suited to expanding control logic in motor control centers and industrial control panels.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"New","offer_id":46268096282858,"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-3rh2911-1ha11-top-mount-auxiliary-contact-block","provider":"GTG Hardware","version":"1.0","type":"link"}
