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.
