Pomanique has been manufacturing the metal-oxide varistor for years and acquired a lot of production experience. The varistor is manufactured in accordance with IEC and ANSI standards in ISO9001 certified factory. Every varistor is subjected to a series of physical and electrical tests to ensure the reliability and protective ability. The varistor with high level of over-voltage protection is widely used in all sorts of surge arresters now.
