WCU8 series surge arrester mainly applies at power line
of AC 50Hz/60Hz, rated operational voltage 230V and 400V
to limit instantaneous over-voltage (lightning induction and
switching over-voltage). It makes the protected electrical
device and parts lower one level at occasion of higher over-
voltage category, and lower down the voltage further when
appled at terminal to protect devices like TV set, high fidelity
sound, air conditioner and computer. It can also matched with
other modular and digital electrics to form combination one of
lightning proof inductive.
