The Deci-Arc tubes are for protection in circuits where high energy transients are anticipated and where size 18 AWG or larger wire sizes are used. They have a 20,000 ampere (8 x 20 usec waveshape) capability and may be used in combination with suitable series resistance for protection on both AC and DC power circuits. Capacitance of these tubes is less than 10pF and initial insulation resistance is greater than 10 ohms.

The spark gaps are available in DC breakdown voltage ranges from 230 to 10,000 volts. Units normally stocked are as follows. Other breakdown voltages available on request.
