    Hello,

    Thinking of installing an Intermatic AG series surge protector across a
    single 110 V line to help protect a circuiit board in a furnace.
    This would be a modelAG2401

    Clamping voltage is given as 490 V.

    Seems awfully high.

    Wouldn't most solid state devices such as PC circuit boards uprocessors,
    etc. blow (well) before this level ?

    Know of any similar point of service wired in units with a lower clamping
    volt. ?

    As always, much thanks for help and info; really appreciate it,
    B.
