Type 1 - AC power surge arrestor, DIN rail mount replaceable surge modules with Iimp 25kA.
FV25B/4-***(S) 4 pole AC surge arrestor is suitable for lightning and surge protection in AC 50/60Hz, 220/380V.
Features of the surge arrestor:
There is a thermal cutoff member inside the AC surge arrestor, when the device is over-current or over-voltage and the puncture is nonseviceable, the thermal cutoff member will automatically separate from the power Lightning Protection Device from the electrical network, and the indication window will turn red from green.
APPLICATION of surge arrestor FV25B/4-***(S):
AC power line of house, bank, telecom tower and so on.
Certificate of the AC surge arrestor:
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.
