Overview
AC operation
IEC 60947, EN 60947 (VDE 0660)
The contactors are suitable for use in any climate. They are
finger-safe according to EN 50274.
The 3RT16 capacitor switching contactors are special variants
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.
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 (in addition to one
NO contact in the basic unit) 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.
In addition, a 2-pole auxiliary contact 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.
For the capacitor making and switching capacity of the basic
3RT10 contactor variant, see Technical Specifications.

This prevents disturbances in the power system and welding of
the contactors.
Only discharged capacitors are permitted to be switched on
with capacitor contactors.
