E-NFS is a competetive structure for the industrial use. The cell centre system is DNV-GL certified, so it is suitable for the most demanding applications.
E-NFS can be made one-sided or twosided, and the variations include L and U -shapes. One cell centre can have more than one bus bar solution. The bus bars can be installed at any height, either in the middle section, in the back or at the top of the center. The bus bars can be made of either aluminium or copper.
Type-tested withdrawable or removable units have been designed for easy maintenance and replacement. The unit structure is compact, and comes equipped with ventilation and locking and a separate compartment for cables and connections.
