Designed to mount alongside the 3VU13\/16 assembly, this block enables simple feedback paths to PLCs or control circuits, remote indicators, interlocks, and basic sequencing in motor protection and automation setups. The unit is specified as an auxiliary contact block for the 3VU family with a 1NO+1NC configuration, providing complementary signaling that changes state in concert with the primary contactor or relay. By preserving the same mounting footprint and electrical characteristics as the base 3VU module, it supports reliable state indication and control logic while keeping wiring organized within compact control panels or switchgear assemblies. Whether used for equipment status indication, interlocking safety logic, or straightforward control loops, the 3VU9131-3AA00 offers a proven, compatible solution for Siemens control schemes that rely on additional, independent contact signaling in conjunction with 3VU13\/16 devices.\u003c\/p\u003e\u003c\/div\u003e","brand":"SIEMENS","offers":[{"title":"New","offer_id":46268193898730,"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-3vu9131-3aa00-auxiliary-contact-block","provider":"GTG Hardware","version":"1.0","type":"link"}
