3. Storing
When the apparatus must be stored for a certain
period of time, our workshops can (on request)
provide suitable packing for the specified storage
conditions.
On arrival, the apparatus must be carefully
unpacked and checked as described in the
Checking on arrival section (chap. 2).
If the apparatus cannot be installed immediately,
it must be repacked in the original packing
materials.
Insert at least one standard packet of special
hygroscopic substance per piece of apparatus
inside the packing.
Should the original packing no longer be available
and the apparatus cannot be installed
immediately, it should be stored indoors in a well-
ventilated, dry, dust-free, noncorrosive
environment, well away from any easily flammable
materials and at a temperature between -5 °C and
+40 °C.
Avoid any accidental impact or positions which
stress the structure of the apparatus.

5. Description
5.1 General
VD4 series circuit breakers are devices under
vacuum for indoor installation. Please refer to the
corresponding technical catalogue code
1VCP000263 for the relative electrical
performance.
Please contact ABB for special installation
requirements.
VD4 series medium voltage vacuum circuit
breakers with lateral operating mechanism for
indoor installation feature the separate pole
construction technique.
Each pole houses a vacuum interrupter which is
encased in the resin when the cylinder is moulded
thanks to a special manufacturing process.
This construction method protects the vacuum
interrupter from shock, pollution and
condensation.
The operating mechanism is the EL trip-free
stored energy type with independent opening and
closing regardless of the operator’s action. The EL
operating mechanism is widely used in all VD4
series circuit breakers with frontal control.
The circuit breaker can be remote controlled when
fitted with dedicated electrical accessories
(gearmotor, opening and closing release).
The operating mechanism, the three poles and the
current sensors (if provided) are installed on a
metal frame without wheels.
The construction is particularly compact, sturdy
and of limited weight.
VD4 series circuit breakers with lateral operating
mechanisms are life-long sealed pressure devices
(Standards IEC 62271- 100 and CEI-EN 62271-100).
Additionally, VD4 series circuit breakers have been
type tested for low temperature and marine
applications (Germanischer Lloyd).

5.4 Standard equipment
5.4.1 VD4/R fixed circuit breakers with rh lateral
operating mechanisms (230 or 300 mm
distance between centers) and VD4/L fixed
circuit breakers with lh lateral operating
mechanisms (230 or 300 mm distance
between centers)
The coded basic version of the fixed circuit
breakers is always the three-pole type and comes
equipped with:
1 opening pushbutton
2 closing pushbutton
3 operation counter
4 circuit breaker open/closed indicator
5 lever for loading the springs in the manual
mode (built into the operating mechanism)
6 indicator for closing springs loaded/relieved.
The basic wiring ends in the terminal box. This
latter is equipped with a withdrawable part that
allows the customer to create a disconnectable
connection (see pictures).
The basic version also includes the following
accessories to be specified at the time of
ordering:
Kit 1 set of five opened/closed auxiliary contacts
or alternatively, with a surcharge, ten or
fifteen auxiliary contacts.
Each shunt opening device uses an NO
auxiliary contact to shut off its power supply
after the circuit breaker has been opened.
This means that there is one NO auxiliary
contact less for every opening release
installed.
Kit 2 opening release
Kit 3 key lock.

5.4.2 Circuit breakers for UniSec switchgear with
rh or lh lateral operating mechanisms
(230 mm distance between centers)
The coded basic version of the circuit breakers for
UniSec switchgear is the same as that of the fixed
circuit breakers, with the following specific
exceptions and equipment:
the dustproof enclosure of the operating
mechanism is equipped with a specific side
frame for the UniSec switchgear
the base is equipped with wheels to make the
switchgear easier to move and rack-in to the
compartment
the wiring ends at the terminal box equipped
with a withdrawable part and can be accessed
without removing the operating mechanism’s
dustproof enclosure. The terminal box is actually
situated at the front and projects over the upper
edge of the enclosure
the front enclosure has a transparent sliding
shutter over the mechanical indicators, the
operating pushbuttons and the hand lever that
loads the closing spring. This protection
prevents hot gas from escaping if an arc forms
in the UniSec circuit breaker compartment. On
request, this shutter can be equipped with a
padlock to prevent it from sliding and thus
inhibit the opening and closing buttons from
being used
9 auxiliary contacts are available on request,
with a surcharge, as an alternative. Since each
shunt opening device uses an NO auxiliary
contact to shut off its power supply after having
opened the circuit breaker, there is an
unavailable NO auxiliary contact for every
opening release installed
on request, this version can be supplied with
just the REF 601 protection device.
