Product Description

Metal oxide surge arrester (MOA) is recognized as the upto-date overvoltage protector which ,due to the inherent superior nonlinear V-A characteristics and steep-wave response of metal oxide varistors ,can suppress overvoltages to a relative low level ,thus providing a reliable protection for insulation of electrical apparatus.
The basic technical parameters are complied with the technical specification of IEEE and IEC60099-4
