3RH, 3TH Contactor Relays
3RH1 contactor relays, 4- and 8-pole
AC and DC operation
Surge suppression
IEC 60947, EN 60947.
RC elements, varistors, diodes or diode assemblies (combination of a diode and a Zener diode) can be plugged onto all contactor relays from the front for damping opening surges in the
coil. The plug-in direction is determined by a coding device.
The 3RH1 contactor relays are suitable for use in any climate.
They are finger-safe according to EN 50274.
The 3RH1 contactor relays have screw or Cage Clamp terminals. Four contacts are available in the basic unit. For expansions see Accessories on page 3/97.
Contact reliability
Note:
The OFF-delay of the NO contact and the ON-delay of the NC
contact are increased if the contactor coils are attentuated
against voltage peaks (noise suppression diode 6 to 10 times;
diode assemblies 2 to 6 times, varistor +2 to 5 ms).
High contact stability at low voltages and currents, suitable for
solid-state circuits with currents > 1 mA at a voltage of 17 V.

3RH14 latched contactor relays, 4-pole
■ Overview
RC elements, varistors diodes or diode assemblies can be fitted
to both coils from the front for damping opening surges in the
coil.
AC and DC operation

The contactor coil and the coil of the release solenoid are both
designed for uninterrupted duty.
The contactor relay can also be switched on and released manually (see note on Technical Information on page 3/1).
The number of auxiliary contacts can be extended by means of
auxiliary switch blocks (up to 4 poles) (see Accessories on page
3/97).

3RH, 3TH Contactor Relays
3TH2 contactor relays, 4- and 8-pole
■ Accessories
AC and DC operation
Auxiliary switch blocks
IEC 60947, EN 60947.
The contactor relays with 4 contacts with screw terminals relays
can be expanded by up to four contacts by the addition of snapon auxiliary switch blocks.
The terminal designations comply with EN 50011.
3TH2 contactor relays
The 3TH2 contactor relays are suitable for use in any climate.
The contactor relays with screw terminal are finger-safe according to EN 50274.
Terminals
The 3TH20 contactors with 4 auxiliary contacts are available with
SIGUT screw terminals, 6.3 mm x 0.8 mm flat connectors and
solder pin connections.
The contactors 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 contactor relays are coded and the plug-in
base is codable in order to ensure non-interchangeability.
The 3TH22 contactor relays with 8 integrated contacts are available with screw terminals. The terminal designations are according to EN 50011.
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 and
higher.
3TH27 latched 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 contactor 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 contactor relays with screw terminals with 4 contacts according to EN 50011, with the identification number 40E, can be
extended with 80E, 71E, 62E, 53E or 44E auxiliary switch blocks
to obtain contactor relays with 8 contacts according to EN
50011. The identification numbers 80E, 71E, 62E, 53E or 44E on
the coded auxiliary switch blocks apply to the complete contactors. These auxiliary switch blocks cannot be combined with
contactor relays with identification number 31E and 33E.
All contactor relays with screw terminals with 4 contacts according to EN 50011, identification number 40E, 31E or 22E, can be
extended with auxiliary switch blocks with identification number
40, 31, 22, 20, 11 or 02 to obtain contactor relays with 6 or 8 contacts according to EN 50005. The identification numbers on the
auxiliary switch blocks apply only to the attached auxiliary
switch blocks.
For a schematic representation of the expansion possibilities
see figure for 3RH1 contactor relays on page 3/98.
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 damp opening surges
in the coil. The unit labeling plate must be removed for this purpose.
It can be snapped onto the attached surge suppressor.
Additional load module
The 3TX4 490-1J additional load module (see Accessories) can
be used by programmable logic controllers to increase the permissible residual current and to limit the residual voltage of semiconductor outputs.
This module ensures the safe opening of 3TH2 and 3TF2 contactors with direct control through 230 V AC semiconductor outputs.
It is accommodated in the same enclosure as the 3TX4 490-3.
surge suppressors and can be plugged into the contactor.

3RH11 coupling relays (interface)
for switching auxiliary circuits, 4-pole
■ Overview
The 3RH11 coupling relays cannot be extended with auxiliary
switch blocks.
DC operation
IEC 60947, EN 60947.
The 3RH11 coupling relays for switching auxiliary circuits are tailored to the special requirements of working with electronic controls.
The coupling relays have a low power consumption, an extended operating range of the solenoid coil and an integrated
surge suppressor for damping opening surges (exceptions:
3RH11 ..-.HB40 and 3RH11 ..-.MB4.-0KT0).
