Product Description
3P+N, 3 phase Class B+C/I+II, type 1+2 surge protection device, DIN rail mount replaceable surge modules Iimp 12kA. Uc: 150V, 275V, 320V, 385V, 440V.
FV40B+C/4 S surge protection device are suitable for lightning and surge protection in AC 50/60Hz, 220/380V.
Features of the surge protector:
There is a thermal cutoff member inside the ge protection 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 arrester FV40B+C/4 S:
AC power line of house, bank, telecom tower and so on.
Certificate of the surge protector:
CE-LVD
