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.

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

configurations. This does not relieve the user from their

responsibility for using good technical working practices

inapplication,installation,serviceandmaintenanceofthe

apparatuspurchased.Shouldfurtherinformationberequired,

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

skilled personnel.

The use of unauthorized spare parts for

repairs to the apparatus, modification of the

apparatus itself, or tampering by unskilled

personnel creates hazardous conditions

which may cause death or serious injury

to people, or damage to the apparatus or

other objects. Carefully follow all the safety

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.

NEPSI.COM - Northeast Power Systems. Inc.

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.

Check that the rated performance of the apparatus is not

exceeded during service.

V. Qualified personnel

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.

NEPSI.COM - Northeast Power Systems. Inc.

The auxiliary power supply only has the aim of keeping the

capacitor charged.

Consumption is therefore minimal.

The power required by the electronic device is indicated in the table below:

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).
