Overview
Tavrida Electric’s outdoor switching module provides the following advantages:
Environmentally friendly
The OSM is an air insulated outdoor switching module.
The patented combined insulation makes it the environmentally friendly option.
The reliability of the design is proven by the worlds most severe climate and pollution conditions test at the Koeberg
Insulator Pollution Test Station (KIPTS) in South Africa.
2
Smallest Dimensions and lowest Weight
Tavrida Electric’s light weight vacuum circuit breaker and the robust aluminium tank contribute to the light weight
of the OSM - not more than 76kg - making these the most light weight outdoor switching modules on the market,
greatly simplifying shipping, handling and installation.
Highest Availability
30,000 C-O operations at rated current and up to 200 operations with full short circuit breaking current without any
maintenance, makes them the most reliable product on the market.
Optimized Measurement
Built-in voltage sensors on all six pole and three current transformers guarantee high accuracy over a wide
measurement range.

Vacuum Circuit Breaker - VCB
Each OSM is equipped with Tavrida Electric’s innovative vacuum circuit breaker (VCB). Tavrida Electric has simplified
the mechanical structure of the vacuum circuit breaker to the greatest possible degree. It uses three single-coil
magnetic actuators, one per pole. All switching elements are assembled along a single axis. All mechanical
movements are therefore direct and linear. The three actuators are mounted in a steel frame and mechanically
linked by a synchronizing shaft. Optimal selection of all components makes these the most compact vacuum
circuit breakers in the world.
Failure of critical components, such as
· mechanical latching
· gears, chains, bearings and levers
· tripping and closing coils
· motors to charge springs
are completely avoided.
2
Maximizing the benefits of the drive mechanism requires vacuum interrupters that combine small dimensions with an
extraordinarily long mechanical and electrical lifespan. The use of a predefined axial magnetic field shape provides
even distribution of current density and consequently substantial improvement of vacuum interrupting performance.
Carefully selected contact material and expert contact design as well as optimized movement and switching speed
result in bounce-free closing.
Substantial increase in mechanical lifespan as well as size reduction of Tavrida Electric vacuum interrupters was achieved
by utilizing metal bellows consisting of welded single discs as opposed to the conventional use of folded steel.
The result is 30,000 C-O cycles at rated current or up to 200 operations at full short-circuit breaking current without
the need to replace or adjust any parts of the vacuum circuit breaker.
Tavrida Electric´s vacuum circuit breaker are entirely maintenance free over a total life expectancy of at least 30 years.

Closing
Closing operation is possible only if manual trip hook is in upper position. 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 of the close capacitors of the CM. As a result the contacts close. At the
same time the opening springs are compressed. In the close position the contacts are kept closed by means
of the magnetic force only. The VCB maintains the closed position without mechanical latching also in case
of a failure of the auxiliary power supply (Figure 4).
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 4).

Manual Trip
When the manual trip hook is pulled down the synchronizing shaft is rotated. A force exceeding the
magnetic attraction forces of the ring magnet is applied to the armature, which subsequently 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.
SM main contacts closed

Manual Closing
The VCB 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 VCB.

Protective Tank
The OSM are constructed from an aluminium tank incorporating the vacuum circuit breaker with single coil magnetic
actuators. The protective tank consists of two main parts: The housing and the bottom protective cover riveted to the
housing. The OSM housing and the cover are made of a corrosion resistant aluminium alloy. Water-tight aluminium
rivets are used to secure the cover. The tank is powder coated in light grey (RAL 7038). The tank including the
control cable cover provides IP65 degree of protection.
Four threaded holes (M12x30) on each side of the tank allow mounting equipment for pole or substation
installation to be fitted. Two of these threaded holes are used to install the set of lifting lugs on the tank.
The earthing provision (M12x30 threaded hole) is labelled for easy identification.

Protective Earthing
For personnel protection the metal housing of the OSM must
be connected according to the applicable regulations, such as
DIN VDE 0141, via the marked earth screw of the OSM to the
earth arrangement of the pole earth bus or substation. The earth
connections can be carried out with cables or flat bar (zinccoated
steel or copper). The cross section must be dimensioned such
that a worst-case fault current (short circuit) does not cause a
weakening of the earth connection (Figure 31).
Tighten the earthing bolt to 30 ± 2 Nm torque.

Liability
Damages and demands for reimbursement of expenses incurred by the customer (in the following: compensation)
for what-ever legal reasons, especially due to non-compliance of obligations of the contractual obligations and for
unauthorized actions, are excluded. This does not apply, insofar as there is a compulsory liability such as according
to the product liability law in cases of malice, gross negligence, because of damage to life, the body or health,
because of damage to important contractual obligations.
Compensation for damage to important contractual obligations, however, is limited to the damage which can be
predicted as typical of the contract insofar as there is no malice or gross negligence, because of damage to life, the
body or health. A change of the obligation to provide proof to the disadvantage of the customer is not connected
with these regulations.
