Alpha BS III 250 Panelboard System up to 630A


Alpha BS III 250 Panelboard

The new Siemens range of panelboard systems take main and sub distribution to another level. The boards fit into the new ALPHA range format from Siemens to offer the specifier and contractor a wider choice. The distributor also benefits because this new design allows the distributor the ability to stock a full range of competitively priced panelboards to cover any eventuality.

We have spoken to consultants and contractors; we have heard their thoughts and listened to their comments. This has enabled us to produce a new range of compact low cost panelboards which will meet the requirements of tomorrow today.
