for making -more time
for breaking-less time why?
when moving contact starts leave from fixed contact
during breaking at that time arc will develope this arc
follow to the moving contact upto rest position of the
contact but arc quench media didnot allow this process
incase breaking cpacity is more means arc presence in
between contact is long time so it is damage the breaker
during making moving contact touch or very near to the
fixed contact on that short time only arc produce
