Three phase 4 poles Class B+C/I+II, type 1+2 surge protective device, DIN rail mount replaceable surge modules Imax 60kA, Iimp 7kA.
FV30B+C/4 surge protective device are suitable for lightning and surge protection in AC 50/60Hz, 220/380V.
Features of the surge protective device:
There is a thermal cutoff member inside the ge protective device, when the device is over-current or over-voltage and the puncture is nonseviceable, the thermal cutoff member will automatically separate from the surgege protective device from the electrical network, and the indication window will turn red from green.
APPLICATION of surge protective device FV30B+C/4-***(S):
AC power line of house, bank, telecom tower and so on.
Certificate of the surge protective device:
CE-LVD
We also can supply DC ge protective device for photovoltaic (PV) system protection 1000VDC, surge arrestor with Imax=60KA, 150KA. And type B surge arrester with spark gap.
