Overview
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 contactors are finger-safe according to EN 50274 (excep-
tion: series resistors S0 to S3). The contactors are available with
both Cage Clamp and screw terminals. The size S00 contactors
have Cage Clamp terminals for all connections. The auxiliary
conductor and coil terminals of sizes S0 to S3 are all Cage
Clamp terminals.
Ambient temperature
The permissible ambient temperature for operation of the
contactors (across the full coil operating range) is -40 °C to
+70 °C.
Uninterrupted duty at temperatures > +55 °C reduces the
mechanical endurance, the current-carrying capacity of the
conducting paths and the operating frequency.
Dimensions
Attaching resistors increases the width of contactor sizes S0 to
S3 (see Dimensional Drawings).
Application
For operation in installations which are subject both to consider-
able variations in the control voltage and to high ambient tem-
peratures, e.g. railway applications under extreme climatic con-
ditions, rolling mills, etc.
Control and auxiliary circuits
The coils of the contactors have an extended tolerance from 0.7
to 1.25 x U
protection against voltage surges. The opening delay is
consequently 2 to 5 ms longer than for standard contactors.
3RT10 ..-0LA0
The DC solenoid systems of the contactors are modified (to
hold-in coil) by means of a series resistor.
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.
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
leads for mounting the 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.
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 leads.

consequently 2 ms to 5 ms longer than for standard contactors.
3RT10 ..-.X.40-0LA2
The contactors are energized using series-connected control
electronics, ensuring the coil operating range of 0.7 to 1.25 x U
at an ambient temperature of 70 °C. They are supplied as
complete self-contained units with a built-on contactor control
unit. A varistor is integrated for damping opening surges in the
coil.
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.
Ambient temperature
The permissible ambient temperature for operation of the
contactors (across the full operating range of the coils)
is -40 °C to +70 °C.
Uninterrupted duty at temperatures > +55 °C reduces the
mechanical endurance, the current-carrying capacity of the
conducting paths and the operating frequency.
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
Dimensional Drawings).
