capacitor. Reducing surging current can avoid transient phenomena and reduction of network voltage. The advance contact with arc extinction is adopted for ARS-QN capacitor contactor. The advance contact closes prior to the main contact and then breaks when the main contact closes to a certain extent. ARS-QN series of products can effectively reduce the impact of surging current on capacitor and avoid transient phenomena and reduction of network voltage. In addition, capacitor contactor improves the anti-interfere capability during use.
Product Name:
ARS-UCM Reactive Compensation Module
Product Model:
QN25 QN33 QN45 QN60 QN70W QN100W
Product Introduction:
ARS-QN capacitor contactor is dedicated to switching detuning or conventional three-phase capacitor. When the contactor is switched to AC network, it will bear the short surging current, several times of the rated current (around 200 times in general), which can lead to the welding for main contact of contactor and may damage the
Product Features:
Excellent control to surging current
Extending average service life of PFC system
Improving power quality (such as avoiding voltage reduction)
Less resistive loss
Longer service life for main contact of capacitor contactor
Advance contact with arc extinction
Longer service life due to soft switching of capacitor
Mal operation prevention and protective resistance
Easy for cable connection
