This 8US1-050-5RK07 device adapter has a width of 45 mm, supports a busbar thickness of 5 mm plus an additional 10 mm, and provides outgoing terminals sized for 1.5 to 4 mm2; it mounts on a 35 mm DIN rail and measures 139 mm in length, with an approximate weight of 0.15 kg. The assembly is rated for 25 A and is listed as discontinued by the manufacturer, reflecting its status as a legacy 8US1 busbar accessory. Typical applications include configuring distributed low-voltage blocks in industrial control panels where a 40 mm busbar center-to-center arrangement and a compact device-adapter footprint are required, leveraging Siemens' busbar system to streamline mounting and connection of compatible circuit breakers within the 8US1 ecosystem.\u003c\/p\u003e\u003c\/div\u003e","brand":"Siemens","offers":[{"title":"Used Surplus - Excellent Condition","offer_id":46268711010538,"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-018.png?v=1788727429","url":"https:\/\/gtghardware.com\/products\/siemens-8us1-050-5rk07-industrial-circuit-breaker","provider":"GTG Hardware","version":"1.0","type":"link"}
