Special Features:

When 20 amps pass between terminals 1 and 2 there shall be continuity between terminals 5 and 6, less than 5 amps no continuity between 5 and 6; when 100 amps pass between terminals 1 and 2 voltage v12 to be 1.0 volts max; when 7kv 250khz applied across terminals 3 and 4 voltage across terminals 1 and 2 to be 30, 000 volts min

Properties:

An item specifically designed for use with fluorescent or mercury vapor lamps and starters to provide a high starting voltage for striking the arc and to stabilize the operating impedance of the circuit in order to maintain the operating current at a steady value.
