First In-House Manufactured Certified Vacuum Interrupters Go To Market
In the first quarter of 2021, Vacuum Interrupters shipped its first set of certified vacuum interrupter replacements that were manufactured in-house.

We also provide vacuum interrupter testers, a combination CT and VT instrument transformer tester, and circuit breaker timers. Additionally, we have a high voltage test laboratory which can be used to evaluate and certify your low- and medium-voltage electrical equipment.

For years we have been working to develop a process that conditions and extends the life of vacuum interrupters by removing unwanted gas molecules from within the canister. The process has been proven in the lab and in the field. We are now able to extend the service life of vacuum interrupters by keeping the internal pressures within an acceptable range for an extended period of time. Our goal is to keep vacuum interrupters in service for more than 100 years.
