Monitor Avoids Hazards of Vacuum Interrupter Failure

The Vacstat Vacuum Interrupter monitor from Thomas & Betts is offers real-time vacuum-loss detection technology. The unique monitor is featured on the Josyln Transmaster, Varmaster and VerSaVac Capacitor Bank Switches. It continuously monitors vacuum integrity while the switch is energized and in service.

In the event of vacuum loss, the VacStat technology provides immediate local and remote vacuum-failure indication and blocks further switch operation to prevent possible equipment damage or personnel injury.

The VacStat incorporates a visual indicator that immediately alerts operators and engineers if the interrupter has lost vacuum and is at risk of failing. This allows immediate action to be taken to protect your valuable resources.
