ted voltage.
The apparatus is protected by a plastic bag,
to prevent any infiltration of water during the
loading and unloading stages and to keep
the dust off during storage. If provided, the
current transformers, support structure and
hardware , supplied on request, are packed
and shipped separately.
2. Checking on receipt:
Circuit-Breaker is dispatched from factory in
three separate cases containing Duct-&-
Poles, Cabinet with Operating
Mechanism
Drive & third case contains Loose Structure
with necessary hardware.
Also make sure that all the materials
described in the shipping note are included
in the supply.
Before carrying out any operation, always make sure that the operating
mechanism springs are discharge
d and that the
apparatus is in the open
position. On receipt, check the state of
the apparatus, that the packing is
undamaged and that the nameplate data corresponds (see fig. 1) with that
specified in the order acknowledgement and in the delivery note.

3. Storage:
When a long period of storage is
foreseen,
(on request) ABB can provide suitable

5. Description:
The OHB medium voltage
circuit-breakers
for outdoor installation use sulphur
hexafluoride gas as insulating and arc
quenching medium. The mechanical
operating mechanism used is ESH type
with stored energy and free release which
allows opening and closing operations
from local and remote positions. The
operating mechanism, the activating
kinematics of the moving contact , all
the
control and operating circuits and the
anti-condensation heater are located
inside the tight metal cabinet which also
acts as the support for t
he poles and Duct.
The above-mentioned structure is
supported by a frame made of t
elescopic
metal sections, which provides the
flexibility to adjust the height of the
circuit breaker from 3090 to 3990 mm.
The Cabinet has IP 54 degree of
protection (if provided with filters
over the ventilation holes on the
bottom of the box - optional) and is fitted
with a tight door
with inspection window.
The door has a
pad-locking arrangement

6.2 Safety indications:
6.3. Circuit-breaker closing and
opening operations
Circuit-breaker operation can be
manual or electrical.
a) Manual operation for spring
charging :
To manually charge the closing springs,
it is necessary to fully insert the
charging lever into the seat (9)
and
turn it clockwise until the yellow
indicator (6) appears. The force which
can normally be applied to the charging
lever fitted is 130 N. In any case, the
maximum force 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:
If mechanical operations are to be carried out on the
circuit-
breaker inside the installation area or with the protection nets
removed, pay great attention to the moving parts and to
the
medium voltage line. If the
operations are disabled, do
not force the mechanical interlocks, instead check that the
operation sequence is correct.
no auxiliary supply 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, press the pushbutton (12).
When there is a shunt closing release, t
operation can also be carried out with
remote control by means of a
circuit. The indicator (11) shows that
closing has been
accomplished.
d) Circuit-breaker opening
For manual opening, press the
(13).
When there is a shunt opening release,
the operation can also be carried out

7. Installation:
7.1. General
7.2. Normal installation conditions
Maximum ambient air temperature + 40 °C
Minimum ambient air temperature (-) 25
°C
Relative humidity % < 95
Altitude < 1000 m
For other installation conditions, please
follow what is indicated in the
product
Standards. For special installation
requirements please contact us. The areas
where
the power
conductors
or auxiliary
circuit conductors are placed must be
protected against the possible access of
animals, which could cause damage to
equipment as well as the installation.
7.3. Preliminary operations
Clean the insulating parts with clean dry
cloth.
Check that the upper and lower terminals
are clean and free of any
deformation
caused by shocks received during
Correct installation is of prime importance for smooth
operation of the product. The instructions given by the
manufacturer must be carefully studied and followed. It
is good practice to use gloves to
handle the parts during
installation.
7.4. Foundation for circuit-breaker
fixing
The foundation for circuit-breaker fixing
must be made of reinforced concrete and
must be smoothly leveled. The maximum
planarity tolerance allowed is 2 x 1000.
The circuit-breaker can be fixed directly to
the floor by means of
four expansion
anchoring bolts (not supplied) or with log
bolts (not supplied).
In the case of fixing
with expansion bolts,
the HILTY HSA M 20x170 type can be
used. In any case, the expansion
anchoring bolts must be of a suitable
type to resist a vertical
extraction force
of 15 kN and a
horizontal traction force
of 20 kN. Refer Fig.6 for Structure
without CTs & Fig.7 for Structure with CTs.
In the case of fixing
with foundation bolts,
these must be made as per Fig.8
