The sectionalizer is applied in 50Hz AC three phase power system with rated voltage range 12-40.5kV.

Working along with recloser or circuit breaker,it is used to isolate fault on overhead power line.

When passage fault occursand the fault current reaches or exceeds preset threshold value, the sectionalizer can memorize the tripping times of upstream recloser.

When it reaches preset times, it drops down to trip automatically.
