Capacitor Switching Contactors
CC Capacitor Contactors are suitable for switching low-inductive and
low-loss capacitors in capacitor banks, without and with reactors.
CC Capacitor Contactors are designed to meet Capacitor Duty application.
Contactors are fitted with block of three early make auxiliary contacts in
series with six quick discharge damping resistors – 2 per phase. These
auxiliary contacts limit peak current in first stage of switching. Subsequently
the nominal current is transferred through main contacts which are switched
in next stage and the auxiliary contacts are switched-off at the same time.
Contactor conform to recommendations IEC-EN 60947-4-1
The main features
. Electrical life
. Reduced watt loss during ‘ON’ condition, saves energy
. Switching of Capacitor bank in parallel without de-rating
