It connects the live wires upstream and downstream of the main switch to earth.
Integration into the interlocking concept prevents the unauthorised switching on and off of the earthing and contact with live parts. At the same time, a key multiplier is integrated into the earthing disconnector.
The earthing disconnector has the following features:
- Small space requirements
- Rugged design
- Minimum maintenance requirements
- Safe operation under difficult conditions
