In addition to the full range of Disconnecting Switches, we feature a comprehensive range of Earthing Switches.
They are available either as stand-alone (with their own post insulator) or integrated with the main switch. Various combinations are possible, from one and up to three integrated earthing blades, in the case of a twin-disconnector layout.
The technologies and materials used for our Earthing Switches are the same as for the Disconnecting Switches, ensuring the highest reliability over years.
According to voltage and short-time current withstand, we propose two kinematics :

•  the single motion design allows an attractive price for medium performance..
• for demanding use, and extended ratings, the double motion type allows the highest performance to comply with every application worldwide.
