Polemount soild dielectric fault interrupters have a total number of unit operations of 116 times by using field-proven vacuum interrupters with high reliability, and are installed on MV distribution lines.
In addition, they guarantee high operating reliability through a compact single drive mechanism with mechanical endurance of 5,000 operations.
The spring for opening operation is charged first before the fault interrupter is closed by electrical operation or manual closing lever.

Used as an sectionalizer in conjucntion with reclosers on MV overhead distribution lines.
Used a fault interrupter to interrupt faults faster than upstream reclosers on the main or branch lines.
Used as a fault interrupter installed at the connection point with distributed energy resources to perform selective protection operation according to the direction of faults.
Used as a load break switch to make or break loads, or to temporarily sectionalize some sections.
