About Surge Suppressors

Surge suppressors are used to protect equipment from transient overvoltages in power, data, and telephone circuits. Surge protection devices carry specifications for maximum surge current, clamping voltage, number of protected lines, and operating temperature. Maximum surge current is the maximum, allowable current for a single impulse waveform with a continuous voltage applied. Higher-level surge current capacities are required for high-exposure applications where very large transients are present. Clamping voltage is the voltage at which surge suppressors conduct their fully-rated current. The number of protected lines is the number of "pairs" or lines protected from power surges. Operating temperature is another important parameter to consider when selecting surge suppressors.
