nerea in functiune a intrerupatoarelor de medie tensiune tip
HD4.
Pentru o utilizare cat mai corecta a acestui tip de intreru-
pator va rugam sa cititi cu atentie acest manual.
Pentru montarea accesoriilor si/sau pieselor de rezerva va
rugam sa cititi paragraful referitor la aceasta parte.
Ca orice aparat fabricat de ABB, intrerupatorul tip HD4 a
fost proiectat pentru functionarea in diferite configuratii.
Aceste aparate pot acoperii diferite variante tehnico-constru-
ctive (la cerearea clientului) pentru a asigura cerintele speciale
de instalare.
Din acest motiv, informatiile prezentate in cele ce urmeaza
nu vor acoperii intotdeauna configuratiile speciale.
Separat fata de acest manual, este necesar a se tine cont
intotdeauna de ultimile documente tehnice disponibile
(diagrame circuite secundare, desene de asamblare si insta-
lare, etc.), in special cand se face referire la variante diferite
de configuratiilor standard.
Toate operatiile de instalare, punere in fuctiune,
operare si mentenanta trebuie realizate de catre

Programul de protectie a mediului inconjurator
Intrerupatoarele tip HD4 sunt construite in conformitate cu
standardele ISO 14000.
Sistemul de productie al fabricii de Echipamente de Medie
Tensiune asigura protectia mediului inconjurator in toate
etapele de fabricare a echipamentelor.
Impactul asupra mediului inconjurator in perioada de functiona-
re este impus de procedura LCA-Life Cycle Assessment, care
este totodata rezultatul unei atentii acordate la alegerea mate-
rialelor, contruirii, etc.
Modul de construire a intrerupatoarelor este facut astfel incat
la depasirea perioadei de viata a echipamentului sa se
poata realiza o separe usoara a toturor subansamblurilor,

Introduction
This publication contains the information necessary for instal-
lation and putting into service of HD4 medium voltage circuit-
breakers.
For correct usage of the product, please read this manual
carefully.
For correct mounting of accessories and/or spare parts please
refer to the relevant instructions.
Like all the apparatus manufactured by us, the HD4 circuit-
breakers are designed for different installation configurations.
They do, however, allow further technical-constructional vari-
ations (at the customer’s request) to suit special installation
requirements.
For this reason, the information given below does not always
cover special configurations.
Apart from this booklet, it is therefore always necessary to refer
to the latest technical documentation available (circuit dia-
gram, wiring diagrams, assembly and installation drawings,
any studies of protection co-ordination, etc.), especially with
regard to any variations from standardized configurations
requested.
All the operations regarding installation, putting
into service, operation and maintenance must be
carried out by suitably qualified personnel with in-
depth knowledge of the apparatus.
Only use original spare parts for maintenance operations.
For further information, also see the technical catalogue of the
circuit-breaker and the spare parts catalogue.
Programme for the environmental protection
The HD4 circuit-breakers comply with ISO 14000 Standards
(Guidelines for the Environmental Management).
The production system of the Medium Voltage factories com-
plies for the environmental protection in terms of energy
consumption, raw materials and waste.
The environmental impact of the product life cycle is assessed
by the LCA - Life Cycle Assessment procedure, which is also
the result of a well-focused project phase in the selection of
materials, processes and packaging.
Production techniques are carried out in order to achieve an
easy dismantling and separation of the components at the end
of the circuit-breaker life cycle, while optimizing the recycling
process.

locks, on the front crosspiece, which allow hooking into the
corresponding joints in the enclosure or fixed part. The locks
can only be activated by the handles with the truck resting
completely on the crosspiece.
The activating lever (connection/isolation) must be fully in-
serted. A lock prevents the truck from advancing into the
enclosure or fixed part (for example when the earthing switch
is closed). With the truck in the middle position between
isolated and connected, the lock prevents closure of the circuit-
breaker (both mechanical and electrical).
On request, a locking magnet can be mounted on the truck
which, when de-energised, prevents truck operation.

6.Instructiuni pentru operarea
intrerupatorului
6.1. Indicatii pentru protectia muncii
Intrerupatorul HD4 asigura un grad minim de pro-
tectie de IP2X daca este instalat in urmatoarele
conditii:
– versiunea fixa, cu sistem de protectie
– versiunea debrosabila, instalat in celula.
In aceste conditii, operatorul este complet prote-
jat impotriva contactului accidental cu partile in
miscare.
Daca trebuie realizata o operatie cu intrerupatorul
scos din celula sau cu sistemul de protectie ne-
realizat, trebuie asigurata o atentie marita la orice
parte aflata in miscare.
Daca anumite operatii nu pot fi realizate trebuie ve-
rificat ce secventa acestora este corecta si nu
se forteaza interblocajele mecanice.
Operatiile de brosare si de debrosare trebuie
realizate gradual pentru a se prevenii orice
impact care poate deforma interblocajele mecanice.

6. Instructions for circuit-breaker
operation
6.1. Safety indications
HD4 circuit-breakers ensure a minimum degree of
protection IP2X if installed under the following
conditions:
– fixed version, with protection netting
– withdrawable version, installed in a switchboard.
Under these conditions, the operator is fully
guaranteed against accidental contact with moving
parts.
Should any mechanical operations be carried out
on the circuit-breaker outside the switchboard or
with the protection netting removed, be very careful
of any moving parts.
If the operations are prevented, do not force the
mechanical interlocks and check that the operation
sequence is correct.
The racking-in and racking-out operations of the
circuit-breaker must be carried out gradually to
prevent any impacts which might deform the me-
chanical interlocks.

6.3. Circuit-breaker closing
and opening operations (fig. 6)
Circuit-breaker operation can be manual or electrical.
a) Manual operation for spring charging
To manually charge the closing springs, it is necessary
fully insert the charging lever into the seat (6) and turn
it clockwise until the yellow indicator (7) appears.
The force which can normally be applied to the charging
lever fitted is 130 N. In any case, the maximum force which
can be applied must not exceed 170 N.
b) Electrical operation for spring charging
On request the circuit-breaker can be fitted with the following
accessories for electrical operation:
– geared motor for automatic charging of the closing springs
– shunt closing release
– shunt opening release.
The geared motor automatically recharges the springs after
each closing operation until the yellow indicator (7) appears.
Should there be no voltage during charging, the geared motor
stops and then starts recharging the springs automatically
when the voltage is on again. It is, however, always possible to
complete the charging operation manually.
c) Circuit-breaker closing
This operation can only be carried out with the closing
springs completely charged.
For manual closing, push the push button (3).
When there is a shunt closing release, the operation can
also be carried out with remote control by means of a control
circuit. The indicator (4) shows that closing has been accom-
plished.
In case of earthing truck with making capacity, activate the
key lock (in the closed position) and remove the key. This is
to prevent accidental opening operations during any main-
tenance work on the installation.
d) Circuit-breaker opening
For manual opening, push the push button (2).
When there is a shunt opening release, the operation can
also be carried out with remote control by means of a control
circuit. The indicator (4) shows that opening has been
accomplished.
6.3. Manevrele de inchidere si deschidere
ale intrerupatorului (fig. 6)
Actionarea intrerupatorului poate fi facuta manual sau electric.
a) Armarea manuala a arcului
Pentru armarea manuala a arcului de inchidere, este nece-
sara introducerea completa a manivelei in orificiul (6)
si invartirea in sensul acelor de ceasornic pana apare
indicatia (7).
Forta ce trebuie in mod normal aplicata este de 130N
si nu trebuie sa depaseasca 170N.
b) Armarea electrica a arcului
La cerere intrerupatoarele pot fi prevazute cu urma-
toarele accesorii pentru actionare electrica:
– motoras de actionare pentru armarea automata a arcului
de inchidere
– bobina de anclansare
– bobina de declansare
Motorasul de actionare armeaza arcul automat dupe fiecare
operatie de inchidere. Daca tensiunea de alimentare dis-
pare motorasul de actionare porneste automat la reaparitia
tensiunii auxiliare. Este deasemenea posibil a se termina
armarea manuala a arcului.
c) Inchiderea intrerupatorului
Aceasta operatie poate fi realizata doar daca arcul de in-
chidere este complet armat.
Pentru inchiderea manuala se apasa butonul (3).
Daca intrerupatorul este prevazut cu o bobina de anclan-
sare inchiderea se poate realiza de la distanta printr-un
circuit de control. Indicatorul (4) confirma inchiderea intre-
ruptorului.
In cazul in care caruciorul a fost pus la pamant, se activeaza
cheia de blocare (in pozitia inchis) si se scoate. Aceasta va
prevenii deschiderea accidentala in timpul operatiilor de
mentenanta.
d) Deschiderea intrerupatorului
Pentru deschiderea manuala se apasa butonul (2).
Daca intrerupatorul este prevazut cu o bobina de decla-
sare aceasta manevra poate fi realizata si de la distanta.
Indicatorul (4) confirma deschiderea intrerupatorului.
