What is the fuction of UV & how it works in circut breakers?
is it one type of relay?

Answer Posted / saleem

UV= Under voltage Coil and this also one type of relay.

In breakars it will sence and give comond to breakar.
I think if the voltage is less than +/-440V or rated
voltage passing through the breakar it will sence.

Mr.Ravikanth as per my knowledgeall the relays will sence
the foult and give comond to breakar for operation.
