Low and medium voltage switchgears
When high reliability and operational safety are necessary.
• This level of reliability can also be provided under difficult climatic and technical conditions.
• It is often a good idea to combine various devices such as isolator / earthing devices or isolator / changeover switches with an earthing device.
Standard size
Earthing switch EES 1 - 2 - 3 … 12 poles
make proof 3.6 - 7.2 - 12 - 24 - 36 kV
Earthing switch GE 1 - 2 - 3 … 12 poles
not make proof 3.6 - 7.2 - 12 - 24 - 36 kV
Isolator NT 1 - 2 - 3 … 12 poles
1 kV up to 3.6 kV - 400 A - 12 kA
GT 1 - 2 - 3 poles
3.6 bis 40.5 kV - 400 A - 12 kA
Changeover switch NT 1 - 2 - 3 … 12 poles U up to 3.6 kV
GT 1 - 2 - 3 … 12 poles U over 3.6 kV
Combi. Isolator/earthing switch GE/NT
