IntroductionElectrical Energy should be distributed safe and controlled For human safety, most of the industrial companies defined, for the operation of their electrical switch gears three lines of defense to avoid accidents by the hazardous potential of electrical energy what are:
Third line: regulation: using special cloth and following the electrical safety rules
Second Line: limitation: additional mechanical measures
First Line: prevention: measures of encapsulation of parts which are alive.
The heart of switchboards in draw‐out‐technology is its contacting‐device, what is responsible to take the energy from the bus‐bar‐system. Prevention means, that the contacting device, the vertical bus‐section and the outgoing‐plug form up a hermetic encapsulation what means an arc‐fault‐ free‐zone. Prevention also means the technical advantages of the pressure‐contacts
