3 poles lightning arrester, DIN rail mount replaceable surge modules with 3 MOV Imax 100kA.
FV50C/3-***(S) 3 poles lightning arrester is suitable for lightning and surge protection in AC 50/60Hz, 220/380V.
Features of the lightning arrester FV50C/3-***(S):
There is a thermal cutoff member inside the lightning arrester, when the device is over-current or over-voltage and the puncture is nonseviceable, the thermal cutoff member will automatically separate from the lightning arrester from the electrical network, and the indication window will turn red from green.
APPLICATION of lightning arrester FV50C/3-***(S):
AC power line of house, bank, telecom tower and so on.
Certificate of the lightning arrester FV50C/3-***(S):
CE-LVD
We also can supply DC Lightning Protection Device for photovoltaic (PV) system protection 1000VDC, surge protective device with Imax=60KA, 150KA. And type B surge arrester with spark gap.
