Jennings Technology designed the first vacuum interrupter in 1955. Since that time, we have been producing high quality and high reliability interrupters for the utility and industrial markets. Jennings interrupter designs handle a wide range of both voltage and current interrupt levels. Vacuum being the most perfect dielectric allows our interrupter designs to have inherent benefits not found in many other interrupter designs.

Vacuum interrupter features:
  • Long life, high reliability
  • Fast interrupting speed
  • Rapid dielectric recovery
  • High cycle withstand voltages
  • Environmentally friendly
  • High cycle withstand voltages
