Denitions
The following abbreviations are used in this operating manual:
AR Automatic reclosing
CM Control module
CO Close open cycle
ISM Indoor switching module
LED Light emitting diode
MCB Miniature circuit breaker
Make time
The make time is the time period from the energising of the closing circuit to the time when the current begins to
ow in the rst pole.
Closing time
The closing time is the time period from the energising of the closing circuit to the time when all three poles make
contact.
Pre-arcing time
Interval of time between the initiation of current ow in the rst pole during a closing operation and the instant
when the contacts touch in all poles for three-phase conditions or 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.
Break time
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.
Open-close time (during AR)
Interval of time between the instant when the arcing contacts have separated in all poles and the instant when the
contacts touch in the rst pole during a reclosing cycle.
Dead time (during AR)
Interval of time between nal arc extinction in all poles in the opening operation and the rst reestablishment of
current in any pole in the subsequent closing operation.
NC Normally closed contact
NO Normally open contact
PCD Pole center distance
SCADA Supervisory control and data aquisition
VCB Vacuum circuit breaker
VI Vacuum interrupter
General
In comparison to conventional circuit breakers, the Tavrida Electric vacuum circuit
breakers comprise of two components:
· The ISM (Figure 1)
· The CM for controlling the ISM and monitoring both modules (Figure 2)
Both modules must only be operated together and are meant for indoor
installations only. The possibility to choose ISM and CM separately allows any type
of switchgear to be easily equipped with regard to its primary and auxiliary circuits.

Compact design
Tavrida Electric develops and produces all vital parts of the circuit breakers themselves. The result of intensive
inhouse fundamental and material research are extremely compact vacuum interrupter and magnetic actuators.
Optimal selection of all components makes these the most compact and light weight vacuum circuit breaker in
the world.
Long life
Contact erosion is minimised by use of axial magnetic eld. All the switching elements are assembled axially and
symmetrically in one straight line. This means that all the mechanical movements are exclusively direct and linear.
30 000 operating cycles can be achieved with rated current without replacing or adjusting any components.
Maintenance free
The ISM is maintenance-free over the expected life of at least 25 years.
Highest availability
In addition to minimising the number of failure-critical components, the Tavrida Electric circuit breaker monitors
its status continuously. In the unlikely event that a fault occurs it is indicated and can be rectied before an unsuc-
cessful switching attempt is made. This leads to higher availability of the electric power supply system.
Design and Method of Operation: ISM and CM
The ISM vacuum circuit breaker uses three single-coil magnetic actuators, one per pole. The three actuators are
mounted in a steel frame and mechanically linked by a synchronizing shaft (Figure 3).

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 of the close capacitors of the CM. As a
result the contacts close. At the same time the opening springs are compressed. In the closed position the
contacts are kept closed by means of the magnetic force only. The ISM maintains the closed position
without mechanical latching also in case 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 be tripped mechanically without auxiliary power supply (emergency trip). It may be opened
manually by means of interlocking shaft rotating counter-clockwise. The interlocking cam of interlocking
shaft act on the armature, when then starts to move (refer to chapter“Installation/Primary part/
Interlocking”, page 24). As the air gap increases, the opening springs and contact pressure springs
overcome any magnetic holding force and the module 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.
