FK Complex Switch for Capacitor Bank

Specifications

No swithing surge current, low looss, no noise, good stability, nice reliability 

It include 3 pcs of independent combination switches, is suitable for switching on /off the low
voltage reactive power compensating capacitor bank. The working theory is that it s contro llable silicon shunt connected with magnetic positioned relay, this will realize that the switching device make or break the capacitor at the moment of ratings through zero via
controllable silicon, and during closing it does not have power loss same as contactor.

1. Switch under zero rating

2. Chipset used for switching on/off and intelligently monitor the controllable silicon, magnetic positioned relay and input power source and load running status, has complete protection functions.

3. No harmonic wave input

4. Low loss
