I am using this 3 Phase voltage protector from 6months and Mashallah its working really well.
It manages all ups n down of voltage fluctuations very easily and saves my electrical appliances.
Make sure get it installed by a professional electrician bcoz not every local electrician understands it.
Must have for all those 3 phase meter users.

I have purchased approx 10 such like protectros both VA as well as VAS model. Excelllent working no issue observed till date. But important thing to note that it would be installed through some technical person not through ordinary electricain.
