Product Description

12kV/5KA Polymer metal oxide surge arrester

Description
The metal oxide surge arrester (MOA) is the most advanced over-voltage protector in the world. The metal oxide varistors(MOV),  as the core organ, made under japanese technology license. It have good response to steep front surge, excellent volt-ampere characteristics and high discharge capability, which provides a very consistent protection merit at steep front surge,lighting surge anf switching surge, and enhances protective capability.

Condition of use
-The ambient air temperatures is no higher than +40ºC, no lower than -40ºC.
-The altitude above sea level does not exceed 2000m.
-AC system frequency is 50HZ or 60HZ.
-AC voltage brought to bear on arrester for a long time does not exceed arrester's continuous operating voltage.
-Maximum wind speed does not exceed 35m/s.
-The earthquake intensity does not exceed 7 degrees.
