Answer Posted / gunasekaran
breaking current is always rms value making current are peak
current. because at the fault condition breaker will be re
closing at sub transient condition. at subtransient
condition current is more so the designed making current
value is less it will burn. so making current always more
than breaking current. it is about 2.5 times of breaking
current.
