Typical Applications

Electrical And Physical Characteristics

The GXP Series of 2-electrode spark gaps are gas discharge tubes,

hermetically sealed in a glass/metal envelope. Tubes with a DC breakdown

voltage in the range 250 V to 10 kV are available. This is signified by a

numeral or numerals following the type letters and is expressed in hundreds

of volts, e.g. GXP60 has a 6kV DC breakdown voltage.

All ratings given in this data sheet a reab solute, nonsimultaneous ratings. It is the equipment designer’s responsibility to ensure

that they are not exceeded.The spark gap life depends on circuit conditions such as peak discharge current and duration,

charge transfer per discharge and the

repetition rate.
