3RT, 3RH, 3TB, 3TC, 3TH, 3TK Contactors for Special Applications
3RT16 Capacitor Contactors
12.5 ... 50 kvar
■ Overview
The contactors are suitable for use in any climate. They are finger-safe according to EN 50274.
The auxiliary switch block which is snapped onto the capacitor
contactor contains the three leading NO contacts and in the
case of S00 one standard NC contact and in the case of S0 and
S3 one standard NO contact, which is unassigned. Size S00 also
contains another unassigned NO contact in the basic unit.
The 3RT16 capacitor contactors are special version of the size
S00 to S3 SIRIUS contactors. The capacitors are precharged by
means of the mounted leading NO contacts and resistors; only
then do the main contacts close.
In addition, a 2-pole auxiliary switch block can be mounted laterally on the 3RT16 47 capacitor contactors (2 NO, 2 NC or 1 NO
+ 1 NC versions); type 3RH19 21-1EA. .. The fitting of auxiliary
switches for 3RT16 17 and 3RT16 27 is not expandable.
This prevents disturbances in the network and welding of the
contactors.

Contactors with Extended Operating Range 0.7 ... 1.25 x Us, for Railway Applications
3RH11 contactor relays
■ Overview
3RH11 22-2K.40-0LA0
DC operation
IEC 60947-4-1, EN 60947-4-1 (VDE 0660, Part 102), for requirements according to IEC 60077-1 and IEC 60077-2.
The contactor relays are finger-safe according to EN 50274. The
size S00 contactor relays have Cage Clamp connections for all
terminals.
The DC solenoid systems of the contactor relays are modified (to
holding excitation) by means of a series resistor.
The size S00 contactor relays are supplied prewired with a plugon module containing the series resistor. The varistor is integrated. A 4-pole auxiliary switch block (according to EN 50005)
can be fitted additionally.
The permissible ambient temperature for operation of the contactor relays (across the full coil operating range) is -40 °C to
+70 °C.
Uninterrupted duty at temperatures > +60 °C reduces the mechanical endurance, the current carrying capacity of the conducting paths and the switching frequency.
At ambient temperatures up to 70°C, the size S00 contactor relays are allowed to be mounted side by side.
3RH11 22-2K.40:
These contactor relays have an extended operating range from
0.7 to 1.25 x Us; the coils are fitted with varistors as standard. An
additional series resistor is not required. Please note:
No auxiliary switch block can be mounted on size S00.
■ Application
Mounting
For operation in installations which are subject both to considerable variations in the control voltage and to high ambient temperatures, e. g. railway applications under extreme climatic conditions, rolling mills, etc.
A clearance of 10 mm is required for side-by-side mounting at
ambient temperatures > 60 °C ≤ 70 °C.
Control and auxiliary circuits
The solenoid coils of the contactor relays have an extended coil
operating range from 0.7 to 1.25 x Us and are fitted as standard
with varistors to provide protection against overvoltage. The
opening delay is consequently 2 to 5 ms longer than for standard
contactors.

■ Overview
■ Application
For operation in plants which are subject both to considerable
variations in the control voltage and to high ambient temperatures, e. g. in railway applications.
DC operation
EN 60947-4-1.
For requirements according to IEC 60077-1 and IEC 60077-2.
The contactors are finger-safe according to EN 50274. Terminal
covers may have to be fitted onto the connecting bars, depending on the configuration with other devices.
3
Ambient temperature
The permissible ambient temperature for operation of the contactors (across the full operating range of the solenoid coil) is 50 to +70 °C. Uninterrupted duty at temperatures < -25 °C and
> +55 °C reduces the mechanical endurance, the current-carrying capacity of the conducting paths and the switching frequency.
Control and auxiliary circuits
The solenoid coils of the contactors have an extended coil operating range from 0.7 to 1.25 x Us and are fitted as standard with
varistors to provide protection against overvoltage. The opening
delay is consequently 2 to 5 ms longer than for standard contactors.
At ambient temperatures > 55 °C, a distance of 10 mm must be
observed if contactor relays and size 1 and 2 contactors are
mounted side by side. There is no need to reduce the technical
specifications.

Uninterrupted duty at temperatures > +60 °C reduces the mechanical endurance, the current carrying capacity of the conducting paths and the switching frequency.
■ Application
For operation in installations which are subject both to considerable variations in the control voltage and to high ambient temperatures, e. g. railway applications under extreme climatic conditions, rolling mills, etc.
■ More information
Control and auxiliary circuits
The solenoid coils of the contactors have an extended coil operating range from 0.7 to 1.25 x Us and are fitted as standard with
varistors to provide protection against overvoltage. The opening
delay is consequently 2 to 5 ms longer than for standard contactors.
3RT10 . .-2K.42-0LA0,
3RT10 . .-3K.44-0LA0
The DC solenoid systems of the contactors are modified (to
holding excitation) by means of a series resistor.
Auxiliary switches
The size S00 contactors are supplied prewired with a plug-on
module containing the series resistor. The varistor is integrated.
A 4-pole auxiliary switch block (according to EN 50005) can be
fitted additionally.
Mounting
At ambient temperatures up to 70°C, the size S00 contactors
and contactor relays are allowed to be mounted side by side.
The resistor module of the size S0 to S3 contactors must be
mounted to the left of the contactor owing to the prefabricated
connecting cables.
Dimensions
Attaching resistors increases the width of contactor sizes S0 to
S3 (see note on Dimensional Drawings, page 3/1).

■ Overview
These contactor relays have an extended operating range from
0.7 to 1.25 x Us; the coils are fitted with varistors as standard. An
additional series resistor is not required.
Please note:
• Size S00: It is not possible to mount an auxiliary switch block.
• Size S0: Up to two single-pole auxiliary switch blocks can be
mounted.
Mounting
A clearance of 10 mm is required for side-by-side mounting at
ambient temperatures > 60 °C ≤ 70 °C.
3RT10 contactors with contactor control unit, extended operating range
3RT10 . .-.X.40-0LA2
They are supplied as complete units with a built-on contactor
control unit.
Control and auxiliary circuits
The contactors are energized via upstream control electronics
which ensure the coil operating range of 0.7 to 1.25 x Us at an
ambient temperature of 70 °C.
A varistor is integrated for damping opening surges in the coil.
The opening delay is consequently 2 to 5 ms longer than for
standard contactors.
The possibility of mounting auxiliary switches is the same as that
for equivalent standard contactors.
Mounting
At ambient temperatures up to 70 °C, sizes S0 to S3 of these
contactor versions are allowed to be mounted side by side.
Dimensions
Because of the built-on contactor control unit, the height of the
size S0 to S3 contactors increases by up to 34 mm (see note on
Dimensional Drawings, page 3/1).
The size S0 to S3 contactors are equipped on the front with an
auxiliary switch block with 2 NO + 2 NC contacts. The separate
series resistor, which is attached laterally next to the contactor
on the 35 mm standard mounting rail, is fitted with connecting
cables for mounting onto contactors. A circuit diagram showing
the terminals is stuck onto each contactor. One NC of the auxiliary contacts is required for the series resistor function. The selection and ordering data shows the number of additional, unassigned auxiliary contacts. It is only possible to extend the
number of auxiliary contacts with size S00.

■ Overview
EN 60947-4-1.
One NC of the auxiliary contacts is required for the series resistor
function. The selection and ordering data show the number of
additional, unassigned auxiliary contacts. It is not possible to extend the number of auxiliary contacts.
For requirements according to IEC 60077-1 and IEC 60077-2.
The contactors are finger-safe according to EN 50274. Terminal
covers may have to be fitted onto the connecting bars, depending on the configuration with other devices.
Reversing contactors
With the 3TB52 to 3TB56 contactors, the series resistor must be
connected using an additional K2 reversing contactor (3RT13
17-1F.40). This contactor is automatically included in the scope
of supply in the same packaging as the contactor.
3
All specifications and technical specifications not mentioned
here are identical to those of the standard 3TB contactors.
Ambient temperature
The permissible ambient temperature for operation of the contactors (across the full operating range of the solenoid coil) is 50 to +70 °C. Uninterrupted duty at temperatures < -25 °C and
> +55 °C reduces the mechanical endurance, the current-carrying capacity of the conducting paths and the switching frequency.
Dimensions
Attaching resistors and varistors increases the width of the contactors (see note on Dimensional Drawings, page 3/1).
■ Application
At ambient temperatures > 55 °C, a distance of 10 mm must be
observed if contactor relays and size 1 and 2 contactors are
mounted side by side. There is no need to reduce the technical
specifications.
For operation in plants which are subject both to considerable
variations in the control voltage and to high ambient temperatures, e. g. in railway applications.
