Metal oxide surge arresters
with polymer housing
We are manufacturing polymer housed metal oxide surge arresters with nominal discharge currents of 5 kA and 10 kA, with rated voltages 3 kV to 36 kV, in accordance with TS-EN 60099-4 and IEC 60099-4.
The optional arrester disconnector is connected in series with the earth lead of the arrester. In case of an arrester failure due to dischargers above rated values, the arrester disconnector disconnects the failed arrester from the system, thereby preventing its being a continuous source of fault. What is more, it enables the site people to identify the failed arrester.
