Features
Extendable fixed-mounted circuit-breaker switchgear of the 8DB10 series is mainly used in
transformer and distribution substations as well as for switching duties in industrial plants.
The panels are designed for rated voltages up to 40.5 kV and rated currents up to 2500 A. In
distribution systems up to 40.5 kV, a maximum short-circuit current of 40 kA is permissible.

When several switchgear sections have to be delivered, the switchgear is delivered ex works
partly with SF
filling ready for service. To fill all gas compartments completely with SF

switchgear section (possible for switchgear assemblies comprising up to 4 panels),
the switchgear is delivered ex works completely with SF
The SF
filling is provided to last the total service life of the switchgear.
