Area of application
The Disconnector type HCD is basically designed for a welding into an aluminium busbar system. This Disconnector is also perfect for the interchange from an aluminium busbar to a copper busbar. One side will be welded into aluminium and the other side will be screwed into a copper busbar.
The Disconnector is equipped with blade-contacts with a robust design. The connection from aluminium to solid silver is according Ritter special welding. This is a lifelong connection silver/aluminium without trouble.
The insulation level refers to normal air conditions at sea level. For installation altitude above 1000 m consider reduction of insulation level.
The Disconnector can be equipped with a small pre-contact to protect the main contacts against rest-voltage during operation.
