Vacuum Capacitor Switch provides 50,000 open/close cycles.
August 13, 2003 - VerSaVac can switch 27 kV ungrounded and 38 kV grounded capacitor banks using vacuum interrupter in conjunction with Joslyteâ„¢ solid insulation system. Pressure equalization system ensures that moisture and contamination will not enter switch over lifetime. Solenoid-driven operating mechanism can operate with as low as 80 Vac and provides synchronized switching, reducing recovery voltage when bank is being switched off.

Versavac Distribution Capacitor Switch Now Available for Use at 27kV Ungrounded and 38kV Grounded Applications
The VerSaVac, which has been the industry leading vacuum capacitor switch for the past 15 years, is now available for switching 27kV ungrounded and 38kV grounded capacitor banks. The VerSaVac uses a long-life vacuum interrupter in conjunction with the proprietary Joslyteâ„¢ solid insulation system to provide a truly maintenance-free device specifically designed for the rugged duty of capacitor switching. The VerSaVac also incorporates a field-proven pressure equalization system to ensure that moisture and contamination will not enter the switch over its life.
The VerSaVac has the longest life of any distribution capacitor switch with the ability to provide 50,000 open and close cycles. The solenoid driven operating mechanism can operate with as low as 80 VAC and provides synchronized switching (less than 4 mS between all poles.) This reduces the recovery voltage when the bank is being switched off, which in turn reduces the electrical stress on the insulation of the capacitor bank.
The VerSaVac can be used in conjunction with the Joslyn Zero Voltage Closing Control which mitigates transients associated with bringing capacitor banks online. The ZVC control eliminates costly customer equipment damage and downtime resulting from voltage spikes. The VerSaVac can also be used with Fisher Pierce capacitor controls ranging from solid-state single function controls to state-of-the-art microprocessor based programmable units.
