Special Features:

For protection in circuits where high energy transients are anticipated and where 18 awg or larger wire sizes are used 20, 000 amps 8 times 20 usec waveshape capability and may be used in combination with suitable series resistance for protection on both ac and dc power circuits, capacitance is less than 10 pf and initial insulation resistance is greater than 10 to the 9th power ohms; contains minute amounts of tritium backfill gas maximun amount 10 microcurie each tube will be identifies with the international radiation symbol h

Properties:

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.
