| Model NO. | Air-insulated switchgear for green application/Ring Main Unit12kV 17.5kV |
| Rated voltage | 17.5kV |
| Rated frequency | 50/60Hz |
| Series | UniGear 500R |
UniGear 500R is very space efficient solution, designed to reduce the width of the medium-voltage airinsulated switchgear. Panel design is only 500 mm wide for feeder current up to 2000 A.Its compact design makes UniGear 500R ideal for container installation for primary distribution.
One of the main characteristics of the UniGear 500R switchgear is the isolation of the circuit-breaker from the main busbars by means of the three position disconnector.
