Repair or Replace Aging Vacuum Interrupters in Your Circuit Breakers

Vacuum Interrupters can provide pole assemblies and replacement vacuum interrupter parts or components for virtually any manufacturer’s medium-voltage circuit breaker.

Extend the Service Life of Vacuum Interrupters in Your Equipment

Knowing how your vacuum interrupters work and how they fail is crucial to extending the life of your electrical equipment and preventing costly damage, downtime, and outages. 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.

We can quickly design replacement or custom vacuum interrupters to fit virtually all types of circuit breakers. Through the Pole Assembly Exchange Program, we can provide complete pole assemblies for many common vacuum circuit breakers. Rental vacuum circuit breakers are also available while yours is being serviced.

If you have vacuum interrupters that may have exceeded their life expectancy or could soon fail, contact us to learn more about testing, repairing, or replacing your devices.
