Arrester,electrical Surge
CAGE
1W8F9

A circuit-protecting device which provides a discharge path for abnormal surges of high potential while consuming little or no power at normal operating voltage. Excludes items which absorb continuously recurring cyclic pulses. For resistors which are sensitive to voltage changes or used as elements in surge arresters, see resistor, voltage sensitive. See also absorber, overvoltage; and cutout disk, protective.
