II. Introduction
This publication contains the information needed to
install medium voltage VD4 circuit breakers and put
them into service.
For correct use of the product, please read it

Like all the apparatus we manufacture, the VD4
circuit breakers are designed for different
installation configurations.
However, this apparatus allows further technical-
construction modifications (at the customer's
request) to adapt to special installation
requirements.
Consequently, the information given below may
sometimes not contain instructions concerning

Apart from this manual, it is therefore always
necessary to consult the latest technical
documentation (electric circuit and wiring
diagrams, assembly and installation drawings, any

Only use original spare parts for maintenance
operations.
For further information, please also see the
technical catalogue of the circuit breaker and the
