General
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.
