Power distribution block BBD40017

4 x 400 A 17 connections multi-stage distribution block (supplied assembled) Quadripolar distribution frames are used to bring together incoming and outgoing electrical circuits at a single point. They are used in tertiary and industrial applications. This 400 A rated quadripolar distribution frame has 17 connections per phase. The operating voltage is 500 Vac. The Zelec range of quadripolar distribution frames covers 160 A to 400 A. The 160 A and 250 A versions can be snapped onto DIN rails and can be mounted onto a plate or base plate. The 400A version can only be installed on a base plate. Our products are delivered ready to use, so all you have to do is install and cable them. One of the highest rated peak withstand currents on the market Our range is one of the most robust on the market, with a rated peak withstand current up to 48 kA. This peak short-circuit current is calculated as a function of the cross section of bar used and the spacing between support. Please contact us for any specific requirements. Ready to use Unlike those of our competitors, the quadripolar distribution frames in the Zelec range are delivered ready to use. There’s no need to assemble the supports and busbars which saves a lot of time when it comes to wiring! High connection capacity Since the connection is made using lugs directly on the copper bars, there is no limits regarding the diameters of your incoming and outgoing cables. Up to 17 connections per phase can be connected to our distribution block. You can increase this capacity by using the C8D and C10D2 connectors.
