Benefits
Advantages
• Plug-in relay with spring-loaded terminals and 6.2 mm width
• Fast exchange with permanent wiring (plug-in relay)
• The wire inlet and terminals can be reached from the front.
This results in faster wiring time and wiring errors are
prevented.
• Tested complete units short mounting time
• Single relays available as components
• Linking of supply voltage and control signals with 16-pole
connecting comb
• Galvanic isolation plate for isolating different voltages for
neighboring units
• Device variants with hard gold-plated contacts, hence high
contact reliability
• 24 V DC version also available as variant with NO contact
• Integrated reverse polarity protection and EMC arc-
suppression diode
• Clearly visible functional state of the relay coupler by yellow
LED
• Safe isolation according to EN 50178
• 230 V AC/DC versions available
■
Selection and ordering data
1) The variants with hard gold-plated contacts feature high contact reliability
(also for low currents) and are therefore especially suitable for steady-
state inputs of programmable logic controllers.

Note:
Logical isolation: 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 isolation is not necessarily safe isolation (see the technical specifications of the relay types).
Safe isolation: Safe isolation prevents voltage of one circuit affecting another circuit with sufficient protection (DIN VDE 106 Part 101).

Overview
Snap-on auxiliary contact blocks
The auxiliary switch blocks and the maximum number of blocks
that can be mounted are described in "Motor Contactors" and
"Contactor Relays".
Solid-state time-delay auxiliary switch block
The timer module, which is available in "ON-delay" and "OFF-
delay" versions, allows time-delayed functions up to 100 s
(3 distinct delay ranges).
It contains a relay with one NO contact and one NC contact;
depending on the version, the relay is switched either after an
ON-delay or after an OFF-delay.
The timer module with "WYE-DELTA FUNCTION" is equipped
with one delayed and one instantaneous NO contact, with an
interval time of 50 ms between the two. The delay time of the
NO contact can be set between 1.5 s and 30 s.
Wye-delta function:
The contactor on which the solid-state, time-delay auxiliary
switch block is mounted operates without a delay.
Size S00
The solid-state, time-delay auxiliary switch block is fitted onto the
front of the contactor. The timer module is supplied with power
directly by plug-in contacts through the coil terminals of the
contactor, in parallel with A1/A2. The timing function is activated
by closing the contactor on which the auxiliary switch block is
mounted. The OFF-delay variant operates without an auxiliary
power supply; minimum on-time: 200 ms.
A varistor is integrated in the timer module in order to damp
opening surges in the contactor coil.
The solid-state, time-delay auxiliary switch block cannot be
mounted on size S00 coupling relays.
Sizes S0 to S12
The solid-state, time-delay auxiliary switch block is fitted onto the
front of the contactor.
The timer module is supplied with power through two terminals
(A1/A2); the time delay of the auxiliary switch block can be
activated either by a parallel link to any contactor coil or by any
power source.
The OFF-delay variant operates without an auxiliary power
supply; minimum on-time: 200 ms.
A single-pole auxiliary switch block can be snapped onto the
front of the contactor in addition to the timer module.
The timer module has no integrated components for damping
opening surges.

The timer module, which is available in "ON-delay" and "OFF-
delay with auxiliary voltage" versions, allows time-delayed
functions up to 100 s (3 distinct delay ranges). Contactors fitted
with a time-delay block close or open after a delay according to
the set time.
The ON-delay variant of the timing relay is connected in series
with the contactor coil; terminal A1 of this coil must not be
connected.
With the OFF-delay variant of the timing relay, the contactor coil
is contacted directly through the relay; terminals A1 and A2 of
the contactor coil must not be connected.
The timing relays are suitable for both AC and DC operation.
Size S00
The version for size S00 contactors is fitted onto the front of the
contactor (with the supply voltage switched off) and then slid
into its latched position; at the same time, the timing relay is
connected by means of plug-in contacts to coil terminals A1 and
A2 of the contactor. Any contactor coil terminals which are not
required are sealed off by means of covers on the enclosure of
the time-delay block, to prevent them from being connected
inadvertently.
A varistor is integrated in the timer module in order to damp
opening surges in the contactor coil.
The solid-state, time-delay block cannot be mounted on size S00
coupling relays.
Sizes S0 to S3
The time-delay block for size S0 to S3 contactors is plugged into
coil terminals A1 and A2 on top of each contactor; the timing
relay is connected both electrically and mechanically by means
of pins.
A varistor is integrated in the timer module in order to damp
opening surges in the contactor coil.
Note on configuration
The activation of loads parallel to the start input is not
permissible when using AC control voltage (see (a) in the circuit
diagram).
The 3RT19 16-2D... / 3RT19 26-2D... OFF-delay timing relay
blocks have a zero potential start input B1. This means that if
there is a parallel load on terminal B1, activation can be
simulated with AC voltage. In this case, the additional load
(e.g. contactor K3) must be wired in accordance with (b).
OFF-delay device for size S00 to S3 contactors
AC and DC operation
IEC 60947, EN 60947
For screw and snap-on mounting onto 35 mm standard
mounting rail. The OFF-delay devices have screw terminals.
The OFF-delay device prevents a contactor from dropping out
unintentionally when there is a short-time voltage dip or voltage
failure. It supplies a downstream, DC-operated contactor with
the necessary power during a voltage dip, ensuring that the
contactor does not trip. The 3RT19 16 OFF-delay devices are
specifically designed for operation with the 3RT contactors and
3RH contactor relays of the SIRIUS series.
The OFF-delay device operates without external voltage on a
capacitive basis, and can be energized with either AC or DC
(24 V version only for DC operation). Voltage matching, which is
only necessary with AC operation, is performed using a rectifier
bridge.
A contactor opens after a delay when the capacitors of the
contactor coil, built into the OFF-delay device, are switched in
parallel. In the event of voltage failures, the capacitors are
discharged via the coil and thereby delay the opening of the
contactor.

If the command devices are upstream of the OFF-delay device
in the circuit, the OFF-delay takes effect with every opening
operation. If the opening operation is downstream of the OFF-
delay device, an OFF-delay only applies in the event of failure of
the mains voltage.
Operation
In the case of the versions for rated control supply voltages of
110 V and 230 V, either AC voltage or DC voltage can be applied
on the line side, whereas the variant for 24 V is designed for
DC operation only.
A DC-operated contactor is connected to the output in
accordance with the input voltage that is applied.
The mean value of the OFF-delay is approximately 1.5 times the
specified minimum time.
Surge suppressors
• Without LED (also for Cage Clamp terminals)
Sizes S00, S0, S2, S3, S6 to S12
• With LED (also for Cage Clamp terminals)
Size S00
All 3RT1 contactors and 3RH1 contactor relays can be retrofitted
with RC elements or varistors for damping opening surges in the
coil. Diodes or diode assemblies (comprising noise suppression
diodes and Zener diodes for rapid switch-off) can be used.
The surge suppressors are plugged onto the front of size S00
contactors. Space is provided for them next to a snap-on
auxiliary switch block.
With all size S0 to S3 contactors, varistors, RC elements and
diode assemblies can be plugged on directly at the coil
terminals, either on the top or underneath.
The plug-in direction of the diodes and diode assemblies is
determined by a coding device.
Coupling relays are supplied either without overvoltage
damping or with a varistor or diode connected as standard,
according to the version.
Note:
The OFF-delay times of the NO contacts and the ON-delay times
of the NC contacts increase if the contactor coils are damped
against voltage peaks (noise suppression diode 6 to 10 times;
diode assemblies 2 to 6 times, varistor +2 to 5 ms).
Electromagnetic interference suppression module, 3-phase
for size S00 contactors
A so-called counter-e.m.f. (electromotive force) is produced
when motors or various inductive loads are turned off. Voltage
peaks of up to 4000 V may occur as a result, with a frequency
spectrum from 1 kHz to 10 MHz and a rate of voltage variation
from 0.1 to 20 V/ns.
Capacitive input to various analog and digital signals makes it
necessary to suppress interference in the load circuit.
Reducing contact arcing
The connection between the main conducting path and the EMC
interference suppression module enables contact arcing, which
is responsible for contact erosion and the majority of clicking
noises, to be reduced; this in turn is conducive to an electromag-
netically compatible design.
Higher operational reliability
Since the EMC interference suppression module achieves a
significant reduction in radio-frequency components and the
voltage level in three phases, the contact endurance is also
improved considerably. This makes an important contribution
towards enhancing the reliability and availability of the system as
a whole.
Dispensing with fine graduations
There is no need for fine graduations within each performance
class, as smaller motors inherently have a higher inductance, so
that one solution for all fixed-speed drives up to 5.5 kW is
adequate.
Two electrical variants are available:
• The advantages of the RC circuit lie mainly in the reduction in
the rate of rise and in its RF damping ability. The selected
values ensure effective interference suppression over a wide
range.
• The varistor circuit can absorb a high energy level and can
also be used for frequencies ranging from 10 to 400 Hz
(closed-loop controlled drives). There is no limiting below the
knee-point voltage, however.

Additional load module
• Size S00 for plugging onto the front of the contactors with and
without auxiliary switch block
Coupling links for mounting on contactors of sizes
S0 to S3
DC operation
IEC 60947 and EN 60947
The coupling link is suitable for use in any climate. It is finger-
safe according to EN 50274. The terminal designations comply
with EN 50005.
System-compatible operation with 24 DC V, operating range
17 V to 30 V.
Low power consumption in conformity with the technical
specifications of the solid-state systems. A light-emitting diode
indicates the circuit state.
Surge suppression
The 3RH19 24-1GP11 coupling link has an integrated surge
suppressor (varistor) for the contactor coil being switched.
Mounting
The 3RH19 24-1GP11 coupling link is mounted directly on the
contactor coil.
Solder pin adapters
The solder pin adapters for the size S00 contactors are available
in two versions:
• Solder pin adapter for contactors with one integrated auxiliary
contact
• Solder pin adapter for contactors with mounted 4-pole
auxiliary switch block
Screw adapters
Plug-on adapters improve the accessibility of the screw fixing for
size S0 contactors. As a result it is possible to position the
screwdriver vertically even when using insulated screwdrivers or
power screwdrivers.
Optionally the adapters can be rotated through 90° before
mounting.
Sealable covers for sizes S00 to S12
When contactors and contactor relays are used in safety-
oriented applications, it must be ensured that it is impossible to
operate the contactors manually.
For SIRIUS contactors there are sealable covers available for
this purpose as accessories; these prevent accidental manual
operation. These are transparent molded-plastic caps with a
bracket that enables the contactor to be sealed.

1) The AC voltages are valid for 50 Hz and 60 Hz.
2) Cannot be fitted onto coupling relays.
3) The terminals for the control supply voltage are connected to the
contactor by the integrated spring contacts of the solid-state time
auxiliary switch above it when this switch is mounted
4) Setting of output contacts in as-supplied state not defined (bistable relay).
Application of the control supply voltage once results in contact
changeover to the correct setting.
5) Terminals A1 and A2 for the control supply voltage of the solid-state time-
delay auxiliary switch must be connected to the associated contactor by
means of connecting leads.
