Vacuum Interrupter

The MAC-TS4 vacuum interrupter test set can easily determine the pressure inside a vacuum interrupter and, along with wear and number of operations, can predict the usable life of the vacuum interrupters used in your circuit breakers and contactors. Until now, this type of testing could only be done at the assembly plant. The MAC-TS4 uses magnetron atmospheric condition (MAC) testing to measure actual ion current against known values to determine vacuum interrupter internal pressure. The MAC-TS4 test set can help avoid unnecessary damage to circuit breakers and contactors by identifying interrupters approaching an unsafe pressure.
