1.1 Application
The vacuum contactors 3TL6 installed in the withdrawable
units are suitable for switching
• HV motors, transformers.
• Other loads with high switching frequency
e.g. arc furnaces or capacitors.
Withdrawable vacuum-contactor boards are thus used in
factories, refineries, drilling platforms, power stations, etc.
1.1.1 Characteristic features of the switchpanel
• Rated voltage up to 12kV.
• Single busbar.
• Rated current.
– of busbar up to 4000A
– of branch 400A
• Factory-built, type-tested for indoor installation
With metal-clad, compartmented panels
Safety of personnel ensured
– Sheet-steel enclosure tested for resistance to accidential
arcing
– Switching on/off the power by vacuum contactor
performed with the door closed
– Isolation from supply can be tested with the door
closed(option)
– Operating compartments segregated by metal partitions

pollution layers
Special features
– Minimum space requirement
– HV contactor and HVHRC fuses on the withdrawable unit
– Easy for move of withdrawable unit and between service
position disconnected position inside the panel
– Exchange of withdrawable units without any problems
– Partition plates and shutters are made of
sendzimir-galvanized sheet steel
– Cable connection from the rear side
– 8BK20 circuit-breaker panels can be arranged side by side
1.2Constrution
1.2.1Mechanical construction
Two individual panels are arranged in a common frame
(double panel); The panel layout, metal enclosure, partition
walls and shutters are shown in Figures 3 and 4.
1.2.2Electrical design
1.2.2.1Main circuit
Busbar (4,Figure 4)
Withdrawable unit including vacuum contactor (Figure 5)
The withdrawable unit is equipped with a 3TL6 vacuum
contactor, the contacts for accommodating the HV fuses.
The withdrawable unit can be moved between the service
and the disconnected positions with a hand crank. In the
disconnected positions by opened door the segregation
between the contact arms and the mating contacts is
assured in according to DIN VDE 0670,Part 6/IEC 298.
