Power Switch HVCB

The plug-in module contains a power switch and is suited for the switching and fuse protection of a high-voltage output in three-phase mains. The use of vacuum switching tubes with a nominal breaking capacity of 31 kAeff at 11 kV makes power fuses superfluous. Fuse failures due to age and the resulting downtimes no longer occur, and time and cost intensive changes are no longer required.
