Contactors (Switches individual capacitor steps via Reactive control Relay)

 

Contactors designed especially for switching low inductive capacitive loads are used.

These contactors are used for switching capacitors mentioned above and are protected against contact welding for a prospective current of 200 x Ie. i.e. 200*72 Amps.

Contactors have magnetically switched early make contacts and damping resistors. These reduce the inrush current to <70 x Ie Contactor Ie rating = 100 Amps
