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
arrester are heavy duty distribution class surge arrester. These are gapless design
incorporating highly non-linear metal oxide varistor, with a discharge rated current of 10 kA. The housing can be polimeric arresters are tested in accordance with the lastest standard ANSI/IEEE C62.11 for metal oxide
arresters, and also with IEC 60099-4.
They consistently withstand the following
minimum type test:
* High Current-Short duration: 2
current surges of 100 kA-crest magnitude
20 shoots of 100 kA amplitude.
* Low Current-Long duration: 20
shoots (or impulses) of 250 A amplitude
and 2.000 μs duration.
* Duty Cycle: 20 discharges with a
current surge of 10 kA magnitude and
8/20 μs wave shape followed by 2 discharges
with a current surge of 100 kA
magnitude.
