3.6kV~500kV Porcelain (composite) Housing Metal-oxide Arrester
MOA is the world-advanced overload protector up to now. Its core elements are formulated from zine oxide. In comparison with traditional silicon carbide arrester, it’s greatly advantaged in property of resistor and current-through capacity under over-voltage. So it’s advantaged completely.

Under normal voltage, the current going through is at level of micro ampere, and the go-through current instantly soar up under over-voltage, thousands of times than the normal value; and the arrester is conductive to release voltage energy, go as to protect contribution facilities against damage effectively.

Application & Features:
Used for protecting power supply facilities against damage by over-load voltage.

Standards:
Comply with IEC 60099-4，GB11032-2000

Type description:

                                               
Note: if it is porcelain housed, without “H”
