The directional recloser prevents malfunction due to reverse fault current in the event of a power-side failure in a line connected to distributed power such as solar,wind,and small power generation. To this end,a directional relay element that determines the magnitude and direction of fault current and operates,is installed and operated on the system power side.

With vacuum cutoff method and epoxy insulation method,it is more eco-friendly because it does not use SF6 gas at all,and maintenance due to gas leakage or replenishment is not required. Due to the excellent insulation performance of epoxy,it can be applied not only to general areas but also to areas that are salted and contaminated. The main body tank and control box are made of stainless steel,which is resistant to corrosion.

By using a magnetic actuator as an operation method,the parts of the main body are simplified and maintenance is convenient,and the opening and closing operation performance of 10,000 times is guaranteed. The control unit adopts the integrated digital method of FRTU that includes a directional relay element.
