I. Introduction
This publication contains the information necessary for
installation 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 circuitbreakers are designed for different installation configurations.
They do, however, allow further technical-constructional
variations (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
diagram, 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 indepth 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.
II. 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
complies 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.
The Product environmental declaration is available for the
HD4 circuit-breakers
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.

5.5. Enclosures and fixed parts
For information about the enclosures and fixed parts, please
consult the relative documentation.
The strikers for activating the contacts (connected/isolated),
located in the enclosure or in the switchgear, are fixed in the
top part of the circuit-breaker. The slides for activating the
segregation shutters of the medium voltage contacts of the
enclosure or switchgear are fixed on the sides of the circuitbreaker. The crosspiece for hooking the circuit-breaker for
the connection/isolation operation by means of the special
operating lever is mounted on the front part of the circuitbreaker truck.
The circuit-breaker is completed with the tulip isolating
contacts. The withdrawable circuit-breaker is fitted with
special 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
inserted. 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.

6.1. 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 switchgear.
Under these conditions, the operator is guaranteed
against accidental contact with moving parts.
Should any mechanical operations be carried out
on the circuit-breaker outside the switchgear 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
mechanical interlocks.
6.2. Operating and signalling parts
Fig. 6
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
accomplished.
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
maintenance 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.
