Air-insulated circuit breaker HCD

high-voltagemodular

High-Current Disconnector "welded type" High-Current Disconnector for the interchange "copper to aluminium" Rated Voltage: up to 3 kV Rated Current up to 180 kA Special versions with up to 440 kA rated current. Welded type for aluminium busbar Perfect interchange from aluminium to copper Safe and visible insulating distance Maintenance free Fail-safe and reliable Long lifetime 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.
