Its IP21-top enclosure and forced cooling (166 m3\/h) distinguish it from the smaller natural-convection braking accessories in the range, and the 780 V DC activation threshold matches the ATV900's DC bus. Pair it only with drives in this power class; larger ATV900 frames need a higher permanent-power braking unit in the same accessory line.\u003c\/p\u003e","brand":"Schneider Electric","offers":[{"title":"Default Title","offer_id":54072449532187,"sku":"VW3A7105","price":3738.47,"currency_code":"USD","in_stock":false}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/0903\/7722\/4475\/files\/schneider-electric-vw3a7105-atv900-braking-unit.jpg?v=1790800509","url":"https:\/\/stoklink.com\/products\/schneider-electric-vw3a7105-atv900-braking-unit","provider":"Stoklink","version":"1.0","type":"link"}
