The 4000 A and up range, proven for many years. The standard version is supplied as a contact pair, i.e. delivered in two non connected halves. This allows the contacts to be set individually according to the bus-bar thickness for installation. The installation distance of the contact halves must be less than the thickness of the bus-bar (depending on the contact block or weight of the bus-bar 4 – 6 mm; consultation required). Inserting the bus-bar works with the bar’s own weight which makes these contacts very efficient for fully automatic operation. Additionally, the bars slide cleans the surface of the contact areas. All contact block sizes can also be delivered as a complete ready-to-install unit with base consisting of a mounting plate and connection bar (flat or angled) as well as the insulation plate. To increase the mechanical stability and to protect the unit against acid and alkaline spillage, we recommend our stainless steel protective covers. The contact units are very maintenance friendly being built according to a modular principle. Complete contact elements (contact fingers including installed foils and fixing accessories) as well as individual replacement foils are available as standard replacement parts.
