180 V to 255 V
Rated output power 1.65 W at 230 V
Permissible contactor types 3RT1.1
3RT1.
Associated coil type P0 (230 V, 50/60 Hz)
N2 (220 V, 50/60 Hz)

Installation The additional load is connected in parallel to the contactor coil. It has the
same construction as the surge suppressor and is attached on the front of
the contactors with or without an auxiliary switch block.
3.4.5 Coupling element for frame sizes S0 to S3 (3RH1924-1GP11)
Field of application The 3RH1924-1GP11 coupling link is intended for contactors of frame sizes
S0 to S3. It can be controlled by a programmable controller output because
the operating range of 17 to 30 VDC is permissible.
Mode of operation A contactor of frame size S0 to S3 can be controlled, for example, at 24 VDC
with a low control level (< 0.5 W) from a programmable controller output.
The control voltage for the coupling link and the rated control supply voltage
for the contactor are electrically isolated. An LED indicates the switching
state of the coupling link.
To dampen switching overvoltages of the contactor coil, a varistor is inte-
grated in the coupling link.
Installation Caution
Switch off the supply voltage applied to L1 and N before installation.

The coupling link is inserted with its
two integrated mounting pins directly
onto the coil connections of the con-
tactor.
