4-pole conductor rail ULA-80354

insulated

4 – pole insulated conductor rails UNILIFT-ULA 35A, 50A, 80A, 100A, 120A Expansion elements The expansion element is applied for compensate the difference in expansion between the conductor rail line and a support structure. In every single line with expansion element, a double current collectors should be used. That will guarantee the conduction continuity and a proper contact of carbon brushes in the expansion element.
