I. Introduction
This publication contains the information needed
to install medium voltage VM1 circuit breakers and
put them into service.
For correct use of the product, please read it
carefully.
Like all the apparatus we manufacture, the VM1
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.
Only use original spare parts for maintenance
operations.
For further information, please also see the
technical catalogue of the circuit breaker.
All the installation, putting into service,
running and maintenance operations
must be carried out by skilled personnel
with in-depth knowledge of the
apparatus.

II. 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.

1. Packing and transport
The circuit breaker is shipped in special packing,
in the open position.
Each piece of apparatus is protected by a plastic
cover to prevent any infiltration of water during
the loading and unloading stages and to keep the
dust off during storage.

When a period of storage is foreseen, our
workshops can (on request) provide suitable
packing for the specified storage conditions.
On receipt the apparatus must be carefully
unpacked and checked as described in Checking
on receipt (chap. 2).
If immediate installation is not possible, the
packing must be replaced, using the original
material supplied.
Insert special hygroscopic substances inside the
packing, using at least one standard packet per
piece of apparatus.
Should the original packing not be available and
immediate installation is not possible, store in a
covered, well-ventilated, dry, dust-free, non-
corrosive ambient, away from any flammable
materials and at a temperature between –5 °C and
+45 °C.
In any case, avoid any accidental impacts or
positioning which stresses the structure of the
apparatus.

Before carrying out any operations, always make
sure that the capacitors are discharged.
To lift and handle the circuit breaker, proceed as
follows (fig. 2):
• use a special lifting tool (1) (not supplied) fitted
with ropes with safety hooks (2);
• insert the hooks (2) in the supports (3) fixed to
the frame of the circuit breaker and lift. Latch
the hooks (2) into the support holes (3)
according to the type of apparatus (see table);
• on completion of the operation (and in any case
before putting into service) unhook the lifting
tool (1) and dismantle the supports (3) from the
frame.
During handling, take great care not to stress the
insulating parts and the terminals of the circuit
breaker.
The apparatus must not be handled by
putting lifting devices directly under the
apparatus itself. Should it be necessary
to use this technique, put the circuit
breaker onto a pallet or a sturdy
supporting surface (see fig. 3). In any
case, it is always advisable to carry out
lifting using the supports (3).

For special installation requirements or other
operating conditions, please contact ABB.
The VM1 type vacuum circuit breakers are
designed for indoor installation in air-insulated
switchgear.
In respect of the technical characteristics, VM1
circuit breakers are suitable for operation of
electric circuits under normal and fault service
conditions.
The vacuum circuit breakers have particular
advantages when used in systems with a high
frequency of operations and/or which lead to a
certain number of short-circuit trips. The VM1
type vacuum circuit breakers stand out for their
particularly high operating reliability, extremely
long useful life expectancy and for being
completely maintenance-free.
The VM1 type vacuum circuit breakers are
available in the fixed and withdrawable version.
The basic structure is shown in the “Technical
data” section.

6. Structure
6.1. Drive structure
The drive is of the magnetic type and basically
consists of the magnetic actuator (6) (fig. 4), the
control module (5), the sensors (10), the
capacitor/s (4) and the kinematics which transmit
the movement to the circuit breaker poles.
The actuator (6) acts on the circuit breaker poles
by means of special kinematics. The capacitor/s
(4) provides/provide the energy required for the
operation.
The mechanical operating positions of the circuit
breaker are detected by two due sensors (10).
The basic version of the circuit breaker is fitted
with the following controls and instruments:
 closing pushbutton “I” (8)
 opening pushbutton “O” (9)
 coupling for manual emergency operation (1)
 mechanical position indicator (2)
 mechanical operation counter (3)
 luminous signalling of the “ready” state (7)
(READY).
It is also possible to install auxiliary open/closed
position contacts (11) (accessory on request).
Fig. 4
6.1.1. Structure of the control module
The control module (5) of the circuit breaker
consists of:
 a microprocessor
 opto-electrical input couplers
 output relay
 electronic power system for controlling the
actuator coils.
