DescriptionGeneral
3TL Vacuum Contactors
3TL vacuum contactors are three-pole contactors
with electromagnetic operating mechanism formedium-voltage switchgear. They are load breaking
devices with a limited short-circuit making
and breaking capacity for applications with high
switching rates of up to 1 million electrical operatingcycles or 3 million mechanical operating cycles.

Switching medium
The vacuum switching technology, proven and fully
developed for more than 30 years, serves as arc-quenching
principle by using vacuum interrupters.
Construction
3TL vacuum contactors consist of a medium-voltage and alow-voltage part. Together with the main conductor
terminals, the vacuum interrupters constitute the
medium-voltage part. All components required to operate
the vacuum interrupter, such as the operating mechanism,
closing latch and control unit make up the low-voltage part.
These components can be arranged either one behind the
other (3TL6) or one above the other (3TL7 and 3TL8).
Application examplesThe vacuum contactors are suitable for operational switching
of alternating current consumers in indoor switchgear, and
can be used, e.g., for the following switching duties:
Motor starting
Plugging or reversing the direction of rotation of motors
Switching of transformers
Switching of reactors
Switching of resistive consumers such as electrical
furnaces
Switching of capacitors.
With these duties, the contactors are used in conveying
and elevator systems, pumping stations, air conditioning
systems as well as in systems for reactive power
compensation, and can therefore be found in almost every
industrial sector.
In contactor-type reversing starter combinations (reversing
duty), only one contactor is required for each direction of
rotation if HV HRC fuses are used for short-circuit protection.

Construction of the 3TL6 vacuum contactor(front view)
3TL6 vacuum contactor
Mode of operation
The atmospheric pressure exerts a force on the metal
bellows of the vacuum interrupter. Without the influence of
the operating mechanism, this would close the contact gap.
The opening springs (6) keep the moving interrupter contact
in open position via the integral rocker (10). To close the
vacuum contactor, the compressive force of the opening
springs (6) is overcome by the magnet system (2). The
magnet armature (4) is attracted, thus moving the integral
rocker (10), which releases the moving interrupter contact
from the open position. The atmospheric pressure closes the
contacts. The integral rocker (10) compresses the contact
pressure springs (16), thus generating the necessary contact
force. When the magnetic excitation is de-energized, theopening springs (6) open the contact gap via the integral
rocker (10) and the moving interrupter contact. The DC
magnet system operates as an economy circuit, proving a
high mechanical endurance and a low pickup and holding
power.
Mechanical closing latch
The latch (7) holds the vacuum contactor in closed position
even without excitation of the magnet system. When themagnet system is energized, the integral rocker is latched
mechanically in the CLOSED position through a lever and
roller system. The vacuum contactor is released electrically
by means of a latch release solenoid (9) or mechanically by
the tripping bolt (8).
Mechanical closing lock-out
The mechanical closing lock-out (5) prevents unintentional
closing of the vacuum contactor, e.g. due to vibrations orwhile racking the withdrawable part. During operational
switching, the closing lock-out is inactive.

3TL6 vacuum contactor (continuation)
Adjustment to the site altitude
At the factory, the vacuum contactor is adjusted to a site
altitude of 200 m to + 1250 m above sea level. For other
site altitudes, the contactor must be adapted to the
corresponding site altitude range by means of adjusters
located on the rear side of the device (see figure on the
right).
Blocking element to interlock two contactors
To interlock two contactors mutually for reversing duty,
a mechanically operating blocking element is available on
request (for 3TL61 only). The blocking element is fixed
between the two contactors, blocking the movement of the
operating rocker of the two contactors alternatively. This
excludes a phase short-circuit that could occur when the two
directions of rotation are activated simultaneously as a result
of mechanical impact and electrical maloperation.
3TL7 vacuum contactor
Construction
3TL7 vacuum contactors have two slim pole shells abovethe operating mechanism. The vacuum interrupters (2) are
fixed between two pole half-shells (1). This design enables
easy and universal installation on the different switchgear
and frame structures. The low-voltage part contains the
magnetic drive, auxiliary contactor and auxiliary contacts.
Mode of operation
The magnetic drive of the 3TL7 vacuum contactor opens and
closes the contacts of the vacuum interrupters. Due to theuse of a special double coil, the magnetic drive is designed
for the closing and holding process.

3TL8 vacuum contactor
Mode of operation
3TL8 vacuum contactors open and close the contacts of the
vacuum interrupters (2). Due to the use of the electronic
economy circuit (12), the magnet system (11) is to a large
extent independent of the voltage type and level.
Mechanical closing latch
The mechanical closing latch (6) holds the vacuum contactor
in closed position even without excitation of the magnet
system (11). The latching module of the mechanical closing
latch (6) is accommodated in the mechanism section.
When the magnet system (11) is energized, the vacuum
interrupter (2) is latched mechanically in CLOSED position
through a lever and roller system. The vacuum contactor is
released electrically by means of a latch release solenoid or
mechanically by a tripping bolt (customer control required).
The command duration for the latch release coil must range
between 100 ms and 1 s. De-energizing must be provided
externally.

Utilization categories
In IEC 60470, power contactors are divided into different
utilization categories. According to these categories, 3TL
vacuum contactors are dimensioned for different electrical
consumers and operating conditions. The opposite table
shows typical applications in accordance with the respective
utilization categories.
Application
3TL vacuum contactors are 3-pole contactors with
electromagnetic operating mechanism for medium-voltageswitchgear. They are load breaking devices with a limited
short-circuit making and breaking capacity for applications
with high switching rates (> 10000 operating cycles).
Vacuum contactors are suitable for operational switching of
alternating-current consumers in indoor switchgear, and can
be used e.g. for the following switching duties:
Switching of three-phase motors in AC-3 or AC-4 operation
Switching of transformers Switching of reactors
Switching of resistive consumers

Switching of motors
3TL vacuum contactors are especially suitable for frequent
operation of motors. As the chopping currents of the
contactors arew 5 A, no unpermissibly high overvoltages are
produced when accelerated motors are switched during
normal operation. However, when high-voltage motors with
starting currents ofw 600 A are stopped during start-up,switching overvoltages may arise. The magnitude of these
overvoltages can be reduced to harmless values by means of
special surge limiters. 3EF surge limiters can be arranged in
parallel to the cable sealing ends, preferably in the cable
compartment. The surge limiters consist of non-linear
resistors (metal-oxide varistors SIOV) and a series-connected
spark gap. During installation it must be observed that the
surge limiter is flexibly mounted on one side for mechanical
reasons.
Switching of transformers
When inductive currents are interrupted, current chopping
can produce overvoltages at the contact gap. Such
overvoltages can be controlled with a protective circuit
composed of 3EF surge limiters.
Switching of capacitors
3TL vacuum contactors can interrupt capacitive currents upto 250 A up to the rated voltage of 12 kV without restrikes,
and thus without overvoltages.
Surge protection via limiters
Overvoltages can arise as a consequence of multiple
restrikes or by virtual current chopping, e.g. when motors
are switched in braked condition or during start-up. Motors
with a starting currentw 600 A are endangered. Safe protec-
tion against overvoltages is ensured by surge limiters; circuitexamples are shown above.

Short-circuit protection via HV HRC fuses
At high short-circuit currents, HV HRC fuses have a
current-limiting effect, i.e. the fuse limits the short-circuit
current to the let-through current. When selecting the fuses,
the type of consumer must be observed, e.g. motor, trans-
former, capacitors.
The diagram shows an example for the coordination of a
HV HRC fuse with an overcurrent-time protection.
Co-ordinating the components of the motor circuit:
The time-current characteristic must be located on the
right of the motor starting current (point A).
The rated current of the HV HRC fuse-link must exceed the
normal current of the motor.
The current corresponding to the intersection B of theHV HRC fuse-link characteristic and the characteristic of the
overcurrent-time protection must be higher than the
minimum breaking current of the HV HRC fuse-link.
If this is not feasible, it must be ensured that overload
currents that are smaller than the minimum breaking current
of the HV HRC fuse-link are interrupted by the switching
device via the striker. This prevents thermal overloading of
the HV HRC fuse-link, which would otherwise be destroyed.
The selected HV HRC fuse link limits the sustained
symmetrical short-circuit current Ik to the let-through current
ID shown in the diagram for the current-limiting
characteristics (ID as a function of IK for HV HRC fuse-links
with different rated currents). The maximum permissible
let-through current is ID = 50 kA.
Requirements
The let-through currentI
D must not exceed 50 kA to 7.2 kV In case of low-voltage supply via a control transformer,
short-circuit currents ranging above the limit switching
capacity must be interrupted within 80 ms This requirement

Short-circuit protection for class E2 controllers
according to UL 347/CSA C22.2
For using 3TL6 and 3TL8 vacuum contactors as class E2
controllers for 7.2 kV, Siemens fuses of type 3GD1 150-4D
(7.2 kV/250 A) or other fuses with a comparable current-
time characteristic are specified for short-circuit protection.
If two fuse-links are connected in parallel, the symmetrical
short-circuit current determined has to be divided by two,
and the associated let-through current for one fuse-link must
be stated. This value must then be multiplied by two in order
to obtain the total let-through current, which must not
exceed the permissible value for the vacuum contactor.
The parallel connection should ensure that the resistance
values in the two branches are almost the same. When the
fuses operate, the vacuum contactor must be switched off.
A suitable device, actuated by the striker of the HV HRC
fuse-link, should be provided.
Fuse monitoring
To prevent a three-phase load (e.g. a motor) from being
supplied only by two phases when a fuse has operated, the
fuse-bases can be equipped with a fuse trip indicator. This
device can be used either to energize a warning signal or to
switch off the vacuum contactor.Short-circuit protection by circuit-breakers
Consumers for which no suitable fuses are available can also
be protected by circuit-breakers. Due to the longer break
time of the circuit-breakers (max. permissible 120 ms), the
symmetrical short-circuit current must not exceed the
maximum permissible value (e.g. 20 kA at 7.2 kV for 3TL6
vacuum contactors). As a consequence of the longer
opening time, the interrupters should be replacedimmediately by new ones after carrying the maximum
permissible symmetrical short-circuit current, as their service
life has been considerably reduced.
Standards
3TL vacuum contactors are designed in open construction,
with degree of protection IP00 according to IEC 60529 and
DIN EN 60529. They conform to the standards for
high-voltage alternating current contactors above 1 kV and
up to 12 kV:
IEC 60470
UL Standard 347
CSA C22.2
As there are no standards available for 24 kV, 3TL7 vacuum
contactors are designed according to
IEC 60470, Edition 05.2000 / DIN EN 60470 Edition
01.2002
DIN EN 62271-100 Edition 01.2004.
Tests
For the development and type testing of power switching
devices, we have accredited testing laboratories at our
disposal:
Testing laboratories with a high electrical testing capacity
Testing laboratories to prove the following features:
Mechanical operation
Reliability Dielectric strength
Temperature-rise performance
Climatic resistance.
To obtain secure results, comprehensive test series are
performed for the type tests defined in the standards.
