  1. Hi there.. I have got a query on replacing a relay on a double booster stabilizer. Runs on 240v and seems to be a relay issue. On the faulty relay currently I have NC as 30A and NO as 40A.. booster has totally 3 delays all 3 have same NC and NO value. 4 KVA capacity, 50 Hz. Currently I have only a NC 20A and NO 30A relay from a single booster. Can I use this less amperes relay? I will be using this in a 1 ton AC . Few pictures attached. Kindly help. Sam
