Area of application

Earthing switches are designed for operator's protection and enable an easy and safe earthing. The Earthing switch ES is without making capacity, the Earthing switch EDS is tested with making capacity. The special type "double blade system" of the EDS is because of the high electrical lifetime specialised for the use in test applications for short-circuit testing. Earthing switches for tunnels or stations can arrange in an emergency case a fast and safe earthing connection. All one- and two-pole earthing switches can be equipped with a motor drive for remote control.

The insulation level refers to normal air conditions at sea level. For installation altitude above 1000 m consider reduction of insulation level.
