specialized for switch detune system and three phase capacitors, reduce the conductive inrush current impact for the capacitors

1. Product Description:

   Contactor for Switching Capacitorsa. WLOW series contactor is specialized for switch between the filter and 3P capacitor.b. When the capacitors exchange to AC network.The capacitor will withstand a trnsient inrush current whitch is exceed several times of rated current. Such inrush current will lead to the main contact of contactor "welding die" , harmful to the capacitor as well.A transient phenomenon and voltage drop can be advoided if reduces inrush current.The adoption of with arc-extinguishing function of leading contact.Those leading contact will closed off before the main contact.And disconnected when the main contact closed to certain extent.             c.the contactor can effectively reduse the conductive inrush current impact for the capactiors,advoided a transient phenomenon and voltage drop .At the same time enhance the anti-interference ability.

2. Feature:

·Advanced surge current suppression·Improve power quality·Capacitor's soft switching gaurantee a long service life of the switch·extension of service life of PFC·less loss of resistance·lead contact  (with the function of arc brush)·resistance protection and prevention of arc brush ·simplified cable connection
