Answer / mukhesh

yes arc should be produced bcz at last trip contacts
induced curent will beconverted into electro static energy
so that is high voltage so at that time air will act as a
dielectric medium so to form arc if arc to be avoided to
dec deelectric medium so voltage will not rise te ability
to produce arc
