COnTACTORS And ASSEMbliES
Siemens / Industrial Controls Previous folio: IC10 2/15
IEC 60947-5, DIN EN 60947-5-1,
(VDE 0660 Part 200)
The contactors are suitable for
use in any climate and are
finger safe per DIN EN 50274.
The 3RT26 capacitor contactors
are application specific variants
of the size S00 to S2 SIRIUS
Innovations contactors. The
capacitors are precharged by
means of the mounted leading
NO contacts and resistors; only
then do the main contacts close.
This prevents disturbances in
the power system and welding
of the contactors.
Only discharged capacitors are
permitted to be switched on
with capacitor contactors.
Recommendation: use dis-
charge chokes for parallel con-
nection with the capacitors.
The capacitor contactors of
size S00 contain either 1NO
or 1NC in the basic unit and
another unassigned NC
contact in the auxiliary switch
block fitted to the basic unit.
The auxiliary switch block
which is snapped onto the
capacitor contactor of sizes
S0 contains the three leading
NO contacts and one stan-
dard NO contact, which is
unassigned.
The capacitor contactors of
size S2 can be fitted addition-
ally with a 2-pole auxiliary
switch on the right side (2 NO,
2 NC or 1 NO + 1 NC), type
3RH19 21-1EA.. for lateral
mounting.
For the capacitor making and
breaking capacity of the basic
3RT20 contactor variant, see
the technical data.
