Integrated thermal-probe protection lets the unit report an over-temperature fault back to the drive rather than relying on external thermal monitoring. It fits Altivar 61, Altivar 71 and Altivar Process ATV900 drives in the 250-315 kW class; drives outside that braking-power range need a smaller or larger unit in the same accessory range.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54072449433883,"sku":"VW3A7101","price":5973.7,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-vw3a7101-altivar-braking-unit.jpg?v=1790800496","url":"https:\/\/stoklink.com\/products\/schneider-electric-vw3a7101-altivar-resistance-braking-unit","provider":"Stoklink","version":"1.0","type":"link"}
