3TL vacuum contactors – The Untiring
3TL vacuum contactors are three-pole contactors with
electromagnetic operating mechanism for medium-voltage
switchgear. They are load breaking devices with a limited
short-circuit making and breaking capacity for applications
Description
General
3TL7/3TL8 vacuum contactors – The Slim 3TL6 vacuum contactor – The Compact
with high switching rates of up to 1 million electrical
operating cycles or 3 million mechanical operating cycles.
As the operating mechanism is located at the rear, 3TL6
vacuum contactors have a very compact design. This arrangement also enables front access to the main conductor
terminals as well as very variable installation options.
In 3TL7 (bottom-right illustration) / 3TL8 (top-right illustration) contactors, the assemblies of the low-voltage part and
of the medium-voltage part are not arranged one behind the
other (3TL6), but one above the other. This provides a slim
design which can easily be mounted on the different switchgear and frame structures.

3TL Vacuum Contactors
1
Application
The vacuum contactors are suitable for operational switching
of alternating current consumers.
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.
Switching medium
The vacuum switching technology, proven and fully
developed for more than 40 years, serves as arc-quenching
principle by using vacuum interrupters.
Construction
3TL vacuum contactors consist of a medium-voltage and a
low-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 assemblies
can be arranged either one behind the other (3TL6) or one
above the other (3TL7 and 3TL8).
Design
3TL vacuum contactors are designed as an open construction, with degree of protection IP00 according to
DIN EN 60529 and IEC 60529.

Description
Construction and mode of operation
3TL6 vacuum contactor
Mode of operation
The atmospheric pressure exerts a force on the metal
bellows of the vacuum interrupter. Without the infl uence 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 closes the interrupter contact. The integral rocker (10) compresses the contact pressure springs
(16), thus generating the necessary contact force. When the
magnetic excitation is de-energized, the opening 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, providing a high mechanical
endurance and a low holding power.
Mechanical closing latch
When the magnet system is energized, the integral rocker
is latched mechanically in the “CLOSED“ position through
a lever and roller system.
The latch (7) holds the vacuum contactor in closed position
even without excitation of the magnet system. The vacuum
contactor is released electrically by means of a latch release
solenoid (9) or mechanically by the tripping bolt (8)
(customer-side control).
Mechanical closing lockout
The mechanical closing lockout (5) prevents unintentional
closing of the vacuum contactor, e.g. due to vibrations or
while racking the withdrawable part. During operational
switching, the closing lockout is inactive.
Built-on components
To interlock two contactors mutually for reversing duty, a
mechanically operating blocking element is available on
request (for 3TL61 only). The blocking element is fi xed
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 senses of rotation are activated simultaneously as a
result of mechanical impacts and electrical maloperation.
Installation position
3TL6 vacuum contactors can be installed in different positions. Besides wall mounting (vertical arrangement), they
can also be mounted on the fl oor (horizontal arrangement).

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 illustration on the right).
3TL7 vacuum contactor
Mode of operation
The mode of operation of the 3TL7 is comparable to the
mode of operation of the 3TL6. Instead of the integral rocker,
the interrupters are operated via a linear mechanical connection (7). Due to the use of a special double coil, the magnetic
drive is designed for the closing and holding process.
Built-on components
To implement a mechanical interlocking between the withdrawable part of the switchgear and the vacuum contactor,
there is a lug (11) available on the operating shaft which
transfers the signaling commands.
Installation position
Contrary to the 3TL6, the 3TL7 can only be installed in
vertical position.
Adjustment to the site altitude
On the 3TL7, the site altitude is selected directly at the 14th
position of the order number. The standard site altitude is
between – 50 m and + 1250 m.
Setting ranges above sea level:
1. + 1250 m to + 2500 m

3TL8 vacuum contactor
Mode of operation
The mode of operation of the 3TL8 is comparable to the
mode of operation of the 3TL6. Due to the use of an electronic module (12), the magnet system (11) is to a large
extent independent of the voltage type and level. The electronic module also takes over the economy circuit.
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.
The vacuum contactor is released electrically by means of
a latch release solenoid or mechanically by a tripping lever
(customer control required).
Built-on components
For no-force components, a long operating shaft (4) is
optionally available.
Installation position
3TL8 vacuum contactors can be installed in different positions. Besides wall mounting (vertical arrangement), they
can also be mounted on the fl oor (vertical or horizontal
arrangement).
Adjustment to the site altitude
The standard site altitude of the 3TL8 is between – 500 m

Utilization categories
In IEC 62271-106, 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 category.
Application examples
3TL vacuum contactors are three-pole contactors with electromagnetic operating mechanism for medium-voltage
switchgear. They are load breaking devices with a limited
short-circuit making and breaking capacity, and are used for
high switching rates (> 10,000 operating cycles).
The 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:
• Three-phase motor starting
• Plugging or reversing the direction of rotation of motors
• Switching of three-phase motors in AC-3 and AC-4
operation
• Switching of transformers
• Switching of reactors
• Switching of resistive consumers such as electrical
furnaces
• Switching of capacitors.
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.

Switching of motors
3TL vacuum contactors are especially suitable for frequent
operation of motors. As the chopping currents of the contactors are ≤ 5 A, no unpermissibly high overvoltages are produced when accelerated motors are switched during normal
operation. However, when high-voltage motors with starting
currents of ≤ 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.
Switching of transformers
When inductive currents are interrupted, current chopping
can produce overvoltages at the contact gap. As the chopping current of the Siemens vacuum contactor is less than
5 A, no dangerous overvoltages are produced when the
unloaded transformer is switched off.
Switching of capacitors
3TL vacuum contactors can interrupt capacitive currents up
to 400 A up to the rated voltage of 24 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 current ≤ 600 A are endangered. Safe protection
against overvoltages is ensured by surge limiters 3EF. These
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 seriesconnected spark gap. During installation it must be observed
that the surge limiter is fl exibly mounted on one side for
mechanical reasons.
Short-circuit protection
3TL vacuum contactors are not designed to switch shortcircuit currents. It is therefore absolutely essential to provide
short-circuit protection. The best protection is provided by
HV HRC fuses, but circuit-breakers can also be used for this
purpose.

Short-circuit protection via HV HRC fuses
At high short-circuit currents, HV HRC fuses have a currentlimiting 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, transformer,
capacitor.
The opposite diagram shows an example for the coordination
of a HV HRC fuse with an overcurrent-time protection.
Coordinating 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 the
HV 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, however, only at 7.2 kV.
Requirements
• The let-through current ID must not exceed 50 kA at 7.2 kV.
• In case of low-voltage supply via a control transformer,
short-circuit currents ranging above the limit breaking capacity must be interrupted within 80 ms. This requirement does
not apply if
– a mechanical latch is provided, or
– the opening times have been extended so much that – in
the a.m. current range – the contactor can only open when
the fuse has interrupted the current.
• Due to the arising motor starting current, the instant when
the motor starts represents the maximum stress for the HV
HRC fuse. This stress must neither operate nor pre-damage
the fuse-link.
• Other factors of infl uence on the stress of the HV HRC
fuses are the starting time and the starting frequency of the
motors.

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 3GD2 150-4D
(7.2 kV/250 A) or other fuses with a comparable current-time
characteristic are specifi ed for short-circuit protection. If two
fuse-links are connected in parallel, the symmetrical shortcircuit 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, has to
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 via 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 break
time, the interrupters should be replaced immediately by
new ones after carrying the maximum permissible symmetrical short-circuit current, as their service life has been
considerably reduced.
Overload protection
For protecting high-voltage motors against overload, it is
possible to use thermally delayed overcurrent relays with
suitable current transformers.
Trip-free mechanism
All contacts of the vacuum contactors are trip-free. The
“OPEN“ command interrupts the “CLOSE“ command, i.e. the
instant of the “OPEN“ command determines whether the
contacts will close or not.
Description
Switching duties, standards and tests
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 highvoltage alternating current contactors:
• IEC 62271-106
• UL Standard 347 (up to 15 kV)
• CSA C22.2 (up to 7.2 kV contactor).
Tests
For the development and type testing of power switching
devices according to relevant standards, 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

Ambient conditions
The vacuum contactors are designed for the normal
operating conditions defi ned in the standards.
Condensation can occasionally occur under the ambient
conditions shown. Vacuum contactors are suitable for use in
the following climatic classes according to IEC 60721:
Climatic ambient conditions: Class 3K4 1)
Class 3K6 2)
Class 3Z2
Class 3Z5
Biological ambient conditions: Class 3B1
Mechanical ambient conditions: Class 3M2
Chemically-active substances: Class 3C2 3)
Mechanically-active substances Class 3S2 4)
1) Low temperature limit: – 25 °C (– 40 °C for 3TL7)
2) Without icing and wind-driven precipitation
3) Without appearance of saline fog and simultaneous condensation
4) Restriction: Clean insulation parts
Dielectric strength
The dielectric strength of air insulation decreases with
increasing altitude due to low air density. According to
IEC 62271-1, the values of the rated lightning impulse withstand voltage and the rated short-duration power-frequency
withstand voltage specifi ed in the chapter “Technical Data“
apply to a site altitude of 1000 m above sea level. For an altitude above 1000 m, the insulation level must be corrected
according to the opposite diagram.
The characteristic shown applies to both rated withstand
voltages.
To select the devices, the following applies:
U ≥ U0 x Ka
U Rated withstand voltage under reference atmosphere
U0 Rated withstand voltage requested for the place of installation
Ka Altitude correction factor according to the opposite diagram
Example
For a requested rated lightning impulse withstand voltage of
60 kV at an altitude of 2500 m, an insulation level of 72 kV
under reference atmosphere is required as a minimum:
72 kV ≥ 60 kV x 1.2

The contactor-fuse combinations 3TL62 / 63 / 66 are
type-tested units of the 3TL6 contactors and HV HRC fuses.
A fuse holder for one or two fuses per phase and optionally
a control transformer for power supply have been integrated.
The type-tested unit enables frequent switching of high normal
currents in a compact space.
The arrangement of the components on the base plate ensures optimum ventilation and thus a high normal current.
This is supported by the specially designed fuse holder,
which ensures uniform current distribution. Even a high
dielectric strength as required in countries such as China are
fulfi lled with this construction. The 3TL6 fuse-link combination is suitable for applications in withdrawable modules
and for fi xed mounting. Bushings and different widths across
fl ats are available for easy integration.
For selection, please use catalog HG 11.22 “Contactor-Fuse
Combinations 3TL62/63/66“.

Order number structure, confi guration example
Order number structure
The vacuum contactors consist of a medium-voltage and
a low-voltage part. The relevant data make up the 12 to
14-digit order number. The medium-voltage part covers the
main electrical data of the poles. The low-voltage part covers
all auxiliary devices which are necessary for operating and
controlling the contactor.
Order codes
Individual equipment versions are explained more in detail
by a 3-digit order code. Several order codes can be added
to the order number in succession and in any sequence.
Special versions ()
In case of special versions, “-Z“ is added to the order number and a descriptive order code follows. If several special
versions are required, the suffi x “-Z“ is listed only once. If a
requested special version is not in the catalog and can therefore not be ordered via order code, it has to be identifi ed
with Y 9 9 after consultation. The agreement hereto is made
directly between your responsible sales partner and the order
processing department in the Switchgear Factory Berlin.
