3.3kV, 6.6kV distribution lightning arrester
Otowa Electric Industry Co., Ltd.
About This Product
■Features
1.No follow current due to non-linear resistance of ZnO element
Suitable for severe lightning surge protection.
2.Excellent protection performance
Since the limiting voltage is sufficiently lower than the JEC standard value, the protection range is expanded.
3.Can be used for a long time without maintenance or inspection
Completely sealed structure requires almost no maintenance or inspection.
