Switching Apparatus

A switching apparatus make it’s a breaker unit, an operating unit, a measuring unit, as well as a controlling unit. The breaker unit is linked on a three-phase current line, as well as includes switches each matching to one of phases of the three-phase current line. The operating unit at the same time turns on or off the switches. The measuring unit measures a current flowing in each phase, as well as determines a time point wherever current flowing in one of the phases turn out to be zero as an orientation time point. The controlling unit controls, at what time interrupting load current, the operating unit toward turn off the switches in a range from 20 degrees toward 40 degrees of an electric angle from the reference time point.
