Connection methods
The contactor relays and the relays are available with screw
terminals (box terminals) or with spring-type terminals.
Screw terminals
Devices of the 3TH2 series are also available with screw
terminals, flat connectors and solder pin connectors.
Spring-type terminals, (push-in)
The 3RQ3 coupling relays are supplied with screw terminals and
spring-type (push-in) terminals. The plug-in bases for LZS/LZX
coupling relays are also available with plug-in (push-in)
terminals.
Flat connectors
As an option the devices of the 3RH2 series are also available
for connection with ring terminal lugs, particularly versions for
North America and Japan.
Solder pin connections
Plug-in terminals (push-in)
3RQ coupling relays: Spring-type push-in connection system
with TOP wiring
Ring terminal lug connections
Push-in connections are a form of spring-type terminals allowing
fast wiring without tools for rigid conductors or conductors
equipped with end sleeves.
The terminals are indicated in the corresponding
tables by the symbols shown on orange backgrounds.
As with other spring-type terminals, a screwdriver (with
3.0 x 0.5 mm blade) is required to disconnect the conductor.
The same tool can also be used to wire finely-stranded or
stranded conductors with no end finishing.
The advantages of the push-in terminals are found, as with all
spring-type terminals, in speed of assembly and disassembly
and vibration-proof connection. There is no need for the
checking and tightening required with screw terminals.
SUVA-certified safety contactors
We offer special safety contactors for use in safety-related
applications. They have NC contacts with mirror contact function
and they have SUVA certification. This means they have
permanently fitted auxiliary switch blocks and cannot be
operated manually. They thus comply with all requirements for
use in safety applications.
With the TOP wiring method, the wire inlet and terminals can be
reached from the front. This helps to speed up the wiring
process and eliminate wiring errors.

The accessories for the 3RT2 contactors in size S00 can also be
used for the 3RH2 contactor relays (see Accessories for 3RT2
contactors, from page 3/54 onwards).
The 3RH2 contactor relays are available with screw, ring terminal
lug or spring-type terminals. The basic unit contains four
contacts with terminal designations according to EN 50011.
Auxiliary switch blocks
The 3RH21 coupling contactor relays for switching auxiliary
circuits are tailored to the special requirements of working with
electronic controls.
Contact reliability
High contact stability at low voltages and currents, suitable for
solid-state circuits with currents ≥ 1 mA at a voltage of ≥ 17 V.
Surge suppression
RC elements, varistors, diodes or diode assemblies (combination of a diode and a Zener diode) can be plugged onto all 3RH2
contactor relays from the front for damping opening surges in
the coil. The plug-in direction is determined by a coding device.
The auxiliary switch block can easily be snapped onto the front
of the contactor relays. The auxiliary switch block has a centrally
positioned release lever for disassembly.

Coupling contactor relays have a low power consumption and
an extended solenoid coil operating range.
Depending on the version, the solenoid coils of the coupling
contactor relays are supplied either without overvoltage
damping (versions 3RH21. .-.HB40 or 3RH21. .-.MB40-0KT0) or
with a diode or suppressor diode connected as standard.

Frequency of contact faults <10-8 i.e. < 1 fault per 100 million operating
cycles
Contact endurance for AC-15/AC-14 and
DC-13 utilization categories
The contact endurance is mainly dependent on the breaking current. It is
assumed that the operating mechanisms are switched randomly, i.e. not
synchronized with the phase angle of the supply system.
If magnetic circuits other than the contactor coil systems or solenoid
valves are present, e.g. magnetic brakes, protective measures for the
load circuits are necessary, e.g. in the form of RC elements and
freewheel diodes.

Contactor Relays
3TH4 contactor relays, 8- and 10-pole
■ Overview
Standards
Surge suppression
IEC 60947-1, EN 60947-1,
IEC 60947-5-1, EN 60947-5-1
The 3TH42 and 3TH43 contactor relays are suitable for use in
any climate. They are finger-safe according to IEC 60529.
The 3TH42 and 3TH43 contactor relays can be equipped with
RC elements, varistors, diodes or diode assemblies (combination of a diode and a Zener diode) for damping opening surges.
The surge suppressors can be mounted directly on the coil
(see page 5/23).
Note:
Note:
The 3TH42 and 3TH43 contactor relays feature positively-driven
operation in accordance with IEC 60947-5-1, Ed. 3.1.
The OFF-delay of the NO contact and the ON-delay of the
NC contact are increased if the contactor coils are attenuated
against voltage peaks (noise suppression diode 6 to 10 times;
diode assembly 2 to 6 times, varistor +2 to 5 ms).
Terminal designations according to EN 50011
Contact reliability
High contact stability at low voltages and currents thanks to the
use of moving double-break contacts, suitable for solid-state
circuits with currents ≥ 1 mA at a voltage of ≥ 17 V.
Mounting
Note:
With 3TH4 contactor relays with AC operation, an overvoltage of
1.1 x Us, an ambient temperature ≥ 45 °C and 100 % ON-period
of all contactors, a minimum clearance of 5 mm between the
contactors shall be observed in the case of side-by-side
mounting.
■ Technical specifications
Contactor relays
Type
3TH42, 3TH43
Contact endurance for AC-15/AC-14 and
DC-13 utilization categories
The contact endurance is mainly dependent on the breaking current. It is
assumed that the operating mechanisms are switched randomly, i.e. not
synchronized with the phase angle of the supply system.
If magnetic circuits other than the contactor coil systems or solenoid
valves are present, e.g. magnetic brakes, protective measures for the
load circuits are necessary.
RC elements or freewheel diodes are suitable as protective measures for
the circuits.

Million operating cycles (10 6 )

In terms of their terminal designations, identification numbers
and identification letters, the 3TH42 and 3TH43 contactor relays
conform to the standard EN 50011 for Specific Contactor Relays.

■ Overview
■ Accessories
Standards
Auxiliary switch blocks
IEC 60947-1, EN 60947-1,
IEC 60947-5-1, EN 60947-5-1
The miniature contactor relays with four contacts with screw
terminals can be expanded by up to four contacts by adding
mountable auxiliary switch blocks (see page 5/30).
The 3TH2 miniature contactor relays are suitable for use in any
climate. The contactors relays with screw terminals are fingersafe according to IEC 60529.
The terminal designations comply with EN 50011.
Connections
5
The 3TH20 miniature contactor relays with four auxiliary contacts
are available with SIGUT screw terminals, 6.3 mm x 0.8 mm flat
connectors, and solder pin connections.
The miniature contactor relays with 6.3 mm x 0.8 mm flat connectors can be used in the plug-in base with solder pin connections
for printed circuit boards. The miniature contactor relays are
coded, and the plug-in base is codable in order to ensure noninterchangeability.
The 3TH22 miniature contactor relays with eight integrated
contacts are available with screw terminals. The terminal designations comply with EN 50011.
Contact reliability
High contact stability at low voltages and currents, particularly
suitable for solid-state circuits with currents ≥ 1 mA at a voltage
of ≥ 17 V.
Latched 3TH27 miniature contactor relays
The contactor coil and the coil of the release solenoid are both
designed for uninterrupted duty.
RC elements, varistors, diodes or diode assemblies can be fitted
to both coils from the front for damping opening surges in the
coil.
The contactor relay can also be switched on and released
manually.
A cover (with unit labeling plate) must be removed from the front
of the miniature contactor relays for this purpose. The auxiliary
switch block is then easy to mount. The auxiliary switch blocks
can be removed again by unlocking them with a laterally
arranged slide.
The miniature contactor relays with screw terminals with four
contacts according to EN 50011 with the identification number
40E can be expanded with 80E, 71E, 62E, 53E or 44E auxiliary
switch blocks to a total of eight miniature contactor relays according to EN 50011. The identification numbers 80E, 71E, 62E,
53E or 44E on the coded auxiliary switch blocks apply to the
complete contactors. They cannot be combined with miniature
contactor relays with identification number 31E and 33E.
All miniature contactor relays with screw terminals with four
contacts according to EN 50011, identification number 40E, 31E
or 22E, can be expanded with auxiliary switch blocks with identification number 40, 31, 22, 20, 11 or 02 to miniature contactor
relays with six or eight contacts according to EN 50005. The
identification numbers on the auxiliary switch blocks apply only
to the attached auxiliary switch blocks.
Surge suppression
RC elements, varistors, diodes or diode assemblies (combination of a diode and a Zener diode for short break times) can be
plugged onto all contactors and auxiliary switch blocks with
screw terminals from the front in order to dampen opening
surges in the coil (see page 5/31).
The unit labeling plate must be removed for this purpose. It can
be snapped onto the attached surge suppressor.
Additional load module
The 3TX4490-1J additional load module (see page 5/31) can be
used by programmable logic controllers to increase permissible
residual current, and to limit residual voltage in semiconductor
outputs.
This module ensures the safe shut-down of 3TH2 contactor
relays and 3TF2 contactors with direct control via 230 V AC
semiconductor outputs. It is accommodated in the same
enclosure as the 3TX4490-3. surge suppressors and can be
plugged into the contactor.

General data
■ Overview
Coupling relays with relay output
AC and DC operation
IEC 60947-5-1, EN 60947-5-1
The input and output coupling relays differ with regard to the
positioning of the terminals and the LEDs.
Coupling relays with plug-in relays
AC and DC operation
IEC 60947-1
The coupling relays are plug-in, so the relay can be replaced
quickly at the end of its service life without detaching the wiring.
Coupling relays with semiconductor output

AC and DC operation
IEC 60947-1, EN 60664-1 and EN 50005;
coupling relays with semiconductor output: EN 60747-5;
programmable controllers: IEC 61131-2
SIRIUS 3RQ3 coupling relays
SIRIUS 3RQ3 coupling relays in narrow design are used for
coupling control signals from and to a controller, and they are
available in different versions:
• Coupling relays with relay output (not plug-in)
• Coupling relays with plug-in relays
• Coupling relays with semiconductor output (not plug-in)
The input and output coupling relays differ with regard to the
positioning of the terminals and the LEDs.
The coupling relays with semiconductor output have extremely
high contact reliability, so they are especially suitable for
electronic systems.
For test purposes, versions are available with manual-0automatic switches.
Spring-type terminal with push-in functionality
Push-in connections are a form of spring-type terminals allowing
fast wiring without tools for rigid conductors or conductors
equipped with end sleeves.
As with other spring-type terminals, a screwdriver (with
3.0 x 0.5 mm blade) is required to disconnect the conductor. The
same tool can also be used to wire finely-stranded conductors
with no end finishing.
The advantages of the push-in terminals are found, as with all
spring-type terminals, in speed of assembly and disassembly
and vibration-proof connection. There is no need for the
checking and tightening required with screw terminals.
Note:
For the conversion tool e.g. from 3TX7 to 3RQ3, see

Coupling Relays
Coupling Relays with LZS/LZX Plug-In Relays
Coupling relays with plug-in relays
■ Overview
Function
The coupling relays with semiconductor output have low power
consumption and are therefore particularly well suited to solidstate systems. In the versions equipped with LEDs, these indicate the switching state. The LZS:PT/MT coupling relays have a
test button. This can be used to force the relays into the
switching state and to lock it without electrical control. This is
indicated by a raised petrol-colored lever.
Control with solid-state output
In the case of solid-state outputs (e.g. proximity switches) with
overload and short-circuit protection, you must make allowance
during configuration for the temporarily flowing capacitor
charging currents! This is possible, for example, by using a suitable LZS coupling relay with plug-in relay.
Surge suppression
The 24 V DC relays LZX:RT and LZX: PT with LEDs can be
supplied with, all others without integral surge suppression
(freewheel diode connected in parallel with A1/A2). The positive
control supply voltage must be connected to coil terminal A1.
Logical separation
The terminals for the contacts and the terminals for the coil are
arranged on separate levels, e.g. above for contacts and below
for coil. Logical separation is not necessarily protective
separation.
Protective separation
For protective separation, transfer of the voltage of one circuit to
another circuit is prevented to a suitable degree of safety
(requirements and tests are described in IEC 60947-1 in
Appendix N).
Notes on the previous LZX series
The complete units and accessory parts of the LZX series are no
longer listed in this catalog. The complete units of the LZS series
are fully compatible with the corresponding units of the
LZX series. Prices for the LZS series are lower than for the
previous LZX series.
The LZX plug-in relays are available unchanged and are used
accordingly in both the LZS and the LZX series.
Note:
Mounting
Due to differences in geometry the LED modules, plug-in bases,
retaining brackets and labels can be combined and/or used in
only the respective series, LZS or LZX.
The relays are plugged into the base and this is snapped onto a
TH 35 standard mounting rail according to IEC 60715.
The LZS series offers not only service-proven screw connections
but also versions with plug-in terminals (push-in).
A retaining bracket can be ordered for the MT series that additionally fixes the relay into a plug-in base (under conditions of
increased mechanical stress). For the RT and PT series, a
combined retaining and ejection bracket is available which can
be used to disassemble the relay where access is difficult, for
example, when relays are mounted side-by-side.
They can be mounted as required.

Note:
Logical separation: The terminals for the contacts and the terminals for the coil are arranged on separate levels, e.g. above for
contacts and below for the coil. Logical separation is not necessarily protective separation.
Protective separation: Protective separation prevents voltage of
one circuit affecting another circuit with sufficient protection
(IEC 61140).
