I. Introduction
The instructions in this manual refer to the fixed and withdrawable
versions of the VSC series of contactors. For correct use of the
product,pleasereaditcarefully.
For the electrical and construction characteristics and the overall
dimensionsoftheV-ContactVSCcontactors,pleasealsosee
technical catalogue 1VCP000165.
Likealltheapparatuswemanufacture,theV-Contactvacuum
contactors are designed for different installation configurations.
Furthermore,thisapparatusallowsfurthertechnicaland
constructionmodications(atthecustomer’srequest)toadaptto
specialinstallationrequirements.Consequently,thismanualmay
not provide information concerning special configurations of the
apparatus.
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. The use
of non-original spare parts can cause hazardous malfunctions
and the apparatus warranty will no longer be valid.
Please refer to the technical sheets of the Kits for correct
assembly of the accessories and/or spare parts. For further
information,alsoseethe1VCP000165technicalcatalogueofthe
contactor and the spare parts catalogue.
This manual and all the enclosed drawings must be considered
an integral part of the apparatus. They must be easily to hand at
all times for revision and reference.
Theseinstructionsdonotintendtocoverallthedetails,
configurationsorvariantsoftheapparatus,storageor
installation.Forthisreason,theinformationgivenbelowmay
sometimes not contain the instructions regarding special

WARNING
Dangerous voltages. Risk of death, serious
injury to people, damage to the apparatus or
other objects.
Before carrying out any maintenance
operations, turn the power supply off and
earth the apparatus.
Read and understand this instruction manual
before installation, service or maintenance of
the apparatus.
Maintenance must only be carried out by

instructions given in this manual.
II. Environmental protection
programme
The V-Contact VSC vacuum contactors 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.

III. Application of the X-ray emission
Standards
One of the physical properties of vacuum insulation is the
possibility of X-ray emission when the interrupter contacts
are open. The tests carried out at the PTB laboratories
(Physikalisch-TechnischeBundesanstalt,inBrunswick-
Germany) show that local emission at a distance of 10 cm
fromtheinterrupterorpolesurface,doesnotexceed
1 µSv/h. It follows that:
– at the rated service voltage the use of vacuum interrupters
is absolutely safe;
–applicationofthewithstandvoltageatpowerfrequency,
accordingtotheIEC62271-1Standard,issafe;
– application of a voltage higher than the withstand voltage
atpowerfrequencyorofadirectcurrenttestvoltage,
specifiedintheIECStandard,cannotbeused;
–limitationoftheabove-mentionedlocalphenomena,on
interrupterswithopencontacts,dependsonkeepingthe
specified distance between the contacts. This condition is
intrinsically guaranteed by correct operation of the drive and
by transmission system adjustments.
IV. Safety information
Alltheinstallation,puttingintoservice,runningand
maintenance operations must be carried out by suitably
qualified personnel with in-depth knowledge of the apparatus.
Make sure that the personnel working on the apparatus
have this manual to hand and all the information required for
correct intervention.
Strictly follow the information given in this instruction manual.
Makesurethatduringtheinstallation,serviceand
maintenance stages the standard and legal requirements
for constructing the installations in accordance with the
regulations for safety in the workplace are respected.

1. Description
The medium voltage V-Contact VSC contactors are pieces
of apparatus suitable for operating in alternating current and
are normally used to control users requiring a high number of
hourly operations.
The basic contactors consist of:
•mouldedpolyesterresinmonobloccontainingthevacuum
interrupters
•bistableelectromagnetactuator
•multi-voltagefeeders
•auxiliarycontacts
•mechanicalstatusindicator(open/closed)
•manualemergencyopeningdevice.
Apartfromwhatisspecifiedforthefixedcontactors,the
withdrawable contactors also consist of:
•fuseholderspresetforDINorBSfuses(accordingtothe
customer’srequirements)
•automaticopeningdeviceforinterventionofevenasingle
fuse
•truck
•lockwhichpreventsclosingduringtheracking-in/out
operation.
The V-Contact VSC contactor introduces the drive with
permanentmagnets-alreadywidelyused,experimented
and appreciated in medium voltage circuit-breakers - into the
worldwide panorama of medium voltage contactors.
The experience acquired by ABB in the field of medium
voltage circuit-breakers fitted with drives with “MABS”
permanentmagnets,hasmadeitpossibletodevelopan
optimisedversionoftheactuator(BistableMACdrive)for
medium voltage contactors.
The drive is operated by means of an electronic feeder able
to cover all the power supply voltages required by the major
international Standards.

1.1. “MAC” magnetic drive
Based on the experience gained in the field of circuit-breakers
withmagneticdrive,ABBhasimplementedthistechnologyin
the field of contactors.
The magnetic drive adapts perfectly to this type of apparatus
thanks to its precise and linear travel.
This means that a simple and direct axial transmission of the
movement to the moving contacts of the vacuum interrupter
canberealised,withbothelectricalandmechanicalbenefits.
Thedrive,whichisofbistabletype,isfittedwithanopening
and a closing coil.
The two coils - individually energised - allow the drive core to
be moved from one of the two stable positions to the other.
The drive shaft is solid with an iron core which is immersed
and held in position in a field generated by two permanent
magnets(fig.A).
Energising the coil opposite to the magnetic latching position
(fig.A)ofthecore,themagneticfield(fig.B)isgenerated,
which attracts and moves the core into the opposite position
(fig.C).
Every opening and closing operation creates a magnetic
field concordant with the one generated by the permanent
magnets,withtheadvantage,duringservice,ofkeeping
the intensity of the field itself constant as the number of
operations carried out increases.
The energy needed for operation is not supplied directly
bytheauxiliarypowersupply,butisalways“stored”inthe
capacitorwhichactsasanenergyaccumulator,andtherefore
operationalwaystakesplacewithconstantspeedsandtimes,
regardless of the divergence of the power supply voltage from
the rated value.

The auxiliary power supply only has the aim of keeping the
capacitor charged.
Consumption is therefore minimal.

Use the ABB S282UC-C3 thermal-magnetic circuit-breaker or
an equivalent type to protect the secondary circuits.
Afterpowering,theelectronicboardtakes15seconds
to perform self-diagnosis and then prepares for normal
operation,dependingontheconfiguration.Donotoperatethe
contactorduringthisphase.ContactDO1willremainopen,
signal “not ready” and will only close after self-diagnosis has
terminated(“ready”state).
Careful selection of the components and a precise design
maketheelectronicmulti-voltagefeederextremelyreliable,
unaffected by electromagnetic interference generated by the
surrounding environment and free of any emissions which may
affect other apparatus placed in the vicinity.
These characteristics have made it possible for the V-Contact
VSC contactors to pass the electromagnetic compatibility
tests(EMC).

During handling, take great care not to
stress the insulating parts of the apparatus
and the terminals of the contactor.
Any operation carried out on the contactor
must be done without the presence of
voltage and with the main protection device
open: danger of electrocution and/or severe
burns.
Make sure that operations are carried out
with the main and auxiliary power off.

truck.
The following precautions must be taken during contactor
handling:
1. Keep the contactor in the upright position.
2. Make sure that the load is balanced on the truck or on the
transport plate/pallet.
3. Interpose protective material between the contactor and
the truck to avoid any damage or scratches.
4. Fix the contactor onto the truck or onto the transport
plate/pallet to prevent it moving or tilting over.
5. Avoidexcessivespeed,suddenstartsandstopsorsharp
changes in direction during contactor handling.
6. Only lift the contactor enough to avoid any obstacles on
the floor.
7. Takecaretoavoidanyimpactswithstructures,other
apparatus or with personnel when handling the contactor.
8. Never lift a contactor over an area where there are people.

4. Storage
Whenaperiodofstorageisforeseen,theoriginalpacking
must be put back. Store the contactor in a dry dust-free
area. It must not be left outside or in adverse micro-climatic
conditions:ifitisleftwithoutprotection,rustanddeterioration
of the insulation can occur.
Insertspecialhygroscopicpacketsinsidethepacking,with
at least one standard packet per piece of apparatus. Replace
the packets approximately every 6 months.
Should the original packing no longer be available and

For altitudes over 2000 m ask ABB.
Climate - Increase in temperature
In order to avoid the risk of corrosion or other damage in
areas with high humidity and/or rapid large fluctuations
intemperature,takeappropriatemeasures(forexample,
using suitable electric heaters) to prevent any condensation
phenomena.
For special installation requirements or other operating
conditions,pleasecontactABB.
5. Installation
5.1. General
Correct installation is of primary importance. The
manufacturer’sinstructionsmustbecarefullystudiedand
followed. It is good practice to use gloves for handling the
pieces during installation.
The areas involved in the passage of power
conductors or conductors of auxiliary
circuits must be protected against access of
any animals which might cause damage or
disservices.
Thecontactorenclosuremustbeinstalledinaclean,dry
and heated place with good ventilation. It must be easily
accessibleforcleaningandinspection,andmustbelevelled,
placed on the supporting foundations and securely fixed into
position.
Whenthecontactorisconnectedtoacapacitiveload,make
sure that there is a heating element to keep the humidity
down and of suitable size for the compartment where the
contactor is installed. The contactor must always be installed
associatedwithasuitableprotectiondevice(e.g.:fuses).
The fixed version of the V-Contact VSC
contactors must be installed by the customer
so as to guarantee a minimum degree of
protection of IP2X.
5.2. Installation and operating
conditions
The following Standards must be taken into particular
consideration during installation and service:
– IEC62271-1/DIN VDE 0101
– VDE 0105: Operation of electrical plants
– DIN VDE 0141: Earthing systems for electrical installations
with rated voltage higher than 1 kV
– All the accident prevention regulations in force in the relative
countries.
