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 vacuum contactors offer one of the most reliable means available for remotely controlling electric power.

The high dielectric strength of a vacuum is one of the important features which distinguishes Jennings vacuum coaxial relays from other types of coaxial relays.
