Hi everyone
have a curious question regarding a star delta panel that I rewired the other day. The motor had two types of protection, thermistors for over temp and and overload setup that consisted of three CTs for the supply mains with a overload factory wired to them. The overload had a range of 1 - 6 A. I assume that this is for phase inbalance but I have never seen this used before. Is this common overload protection control?
