SL - three-position SF6-insulated MV switching devices 10,20 kV

SF6 load break switches are designed for switching circuits with currents up to 630 A in 6 kV, 12 kV, and 20 kV / 50 Hz three-phase a.c. networks with isolated or impedance-grounded neutral.

SF6 disconnectors are designed for switching circuits at no load with currents up to 1000 A in 6 kV, 12 kV, and 20 kV / 50 Hz three-phase a.c. networks, as well as for providing safety during maintenance of electrical installations.
