Revision 1

The following application guide contains information necessary for the methods of
use, installation, commissioning and operation of the ISM_LD series of breakers.
It is absolutely necessary for the proper use of the vacuum circuit breakers to read
this guide carefully before starting and to adhere to the instructions as well as the
relevant regulations.
Safety first
· Check whether the installation position (distances, spatial separation, and the
surroundings) is suitable for the switching devices.
· Installation, operation and maintenance shall only be carried out by trained and
experienced personnel who are familiar with the equipment and the electrical
safety requirements.

The make time is the time period from the energising of the closing circuit to the time when the current
begins to flow in the first pole.
Closing time
The closing time is the time period from the energising of the closing circuit to the time when all three
poles have contact.
Pre-arcing time
Interval of time between the initiation of current flow in the first pole during a closing operation and the
instant when the contacts touch in all poles for three-phase conditions and the instant when the contacts
touch in the arcing pole for single-phase conditions.
Opening time
The opening time is the time period from energising of the closing circuit up to the time when all the
switching poles are separated.

The break time is the time period from the energising of the closing circuit up to the time when the arcs
of all the poles are extinguished.

Interval of time between the instant when the arcing contacts have separated in all poles and the instant
when the contacts touch in the first pole during a reclosing cycle.
Dead time (during AR)
Interval of time between final arc extinction in all poles in the opening operation and the first
reestablishment of current in any pole in the subsequent closing operation.

Scope
In comparison to conventional circuit breakers, the Tavrida Electric vacuum circuit breakers is comprised of two
components:
· The ISM (Figure 1)
· The CM for controlling the ISM (Figure 2)
Both modules must only be operated together and are meant for indoor installations only. The possibility to choose
the ISM and CM separately allows any type of switchgear to be easily equipped with regard to its primary and
auxiliary circuits.
This guide contains information on the operation, installation, commissioning and testing of the Tavrida
ISM_LD series of breaker products.

Closing
In the open position the contacts are kept open by the force of the opening springs. To close
the contacts the coils of the magnetic actuators are excited by a current impulse from the close
capacitors of the CM. The opening springs are compressed when the contacts close. In the closed
position the contacts are kept closed only by means of the magnetic force. The ISM maintains the
closed position without mechanical latching even in the event of a failure of the auxiliary power
supply (Figure 5).
Opening
To open the contacts a current impulse in the reverse polarity derived from the opening capacitors
of the CM is injected in the coils of the magnetic actuators, releasing the magnetic holding force.
The compressed opening springs and contact pressure springs open the contacts (Figure 5).
Manual-Emergency-Tripping
The ISM can also be manually opened. When the synchronizing shaft is rotated, a force exceeding
the magnetic attraction forces of the ring magnet is applied to the armature, which subseqently
starts to move. As the air gap increases, the opening springs and the contact pressure springs
overcome the magnetic holding force, and the vacuum interrupter opens.
Manual Closing
The ISM can only be closed electrically via the CM. In the case of a failure of auxiliary power
supply the contacts can be closed using an alternative auxiliary power supply such as a battery.
Mechanical closing is not possible and leads to the destruction of the ISM.

ISM Installation
General, Preparation
All applicable regulations must be adhered to during installation, commissioning and operation, including
ANSI, IEEE, CEC, NEC, and other local, national or international standards / codes as required. Work shall
only be performed by qualified personnel.
The wearing of gloves for handling the parts during installation
is recommended.
Insulating material surfaces must be cleaned with clean and
dry rags. The contact surfaces of connections must be cleaned
before installation. If the contacts have become oxidized during
transport or storage then the following sequence must be
followed:
· Clean contact surfaces with a rough, dry cloth.
· With hard oxidation, clean with a hard plastic sponge,
the upper layer must not be removed.
Nuts, washers and conical spring washers shall be used for
connecting the upper terminals of the ISM with the busbars.
The lower terminals of the ISM shall be connected with the
same connecting elements.
If additional fastening material is required, steel bolts according
to EN ISO 898 class 8.8 (800 N/mm²), nuts according to EN ISO
890 class 8 (880 N/mm²), washers to DIN 125 and conical spring
washers to DIN 6796 shall be used.
ISM mounting and connection shall be made with dynamometic
wrench only.
Installation of the ISM
All LD series can be installed in any position (Figure 21). The ISM
shall be installed at the place designated for it (Figure 21) on a
sufficiently stable frame.
In order to prevent bending loads at the support insulators the
poles must be fixed as shown in Figure 22.
The torque of all fixing points shall not exceed the values stated
in Figure 23.
