    Overvoltage detector and protection 220v

    Hi, I am looking for a device or way of protection single phase 220v equipment from overvoltage. There is a device AVS30 from www.sollatek.com that does this, however if the voltage is above 320v then the AVS30 is itself damaged. Is there something that would protect up to 400v. thanks John
