Foreword

1.1. Introduction
This publication contains the information needed to install
medium voltage Vmax/W and Vmax circuit-breakers and put
them into service.
For correct use of the product, please read it carefully.
Like all the apparatus we manufacture, the Vmax/W and
Vmax circuit-breakers are designed for different installation
configurations.
However, they do allow further technical and construction
modifications (at the customer's request) to adapt to special
installation requirements.
For this reason, the information given below may sometimes
not contain instructions concerning special configurations.
Apart from this manual, it is therefore always necessary to
consult the latest technical documentation (circuit and wiring
diagrams, assembly and installation drawings, any protection
coordination studies, etc.), especially regarding any variants
requested in relation to the standardised configurations.
For example, the racking and interlock sections do not apply
to the fixed mount breaker styles. All information in this
booklet was current at the time of printing. Unless otherwise
noted, all references in this booklet are determined by viewing
the circuit-breaker from the front.
Only use original spare parts for maintenance operations.
For further information, please also see the technical
catalogue of the circuit-breaker.

1.2. Environmental protection programme

The VM1 circuit-breakers are manufactured in accordance
with the ISO 14000 Standards (Guidelines for environmental
management).
The production processes are carried out in compliance
with the Standards for environmental protection in terms of
reduction in energy consumption as well as in raw materials
and production of waste materials. All this is thanks to
the medium voltage apparatus manufacturing facility
environmental management system.
