NEW! POWER MONITORING & PROTECTION APPLYING SURGE PROTECTORS Surge protectors are relatively simple devices, yet they must be carefully selected and applied to function properly. When selecting and applying surge protectors, there are a few essentials to keep in mind. First, the operating voltage of the system is important. Surge protectors are voltage sensitive switches and must not clamp the normal system voltage. The surge protector clamp voltage must be higher than the system voltage.
