Vacuum Interrupters, Inc. Introduces Rigid Magnetic Coil for MAC-TS4 Vacuum Interrupter Tester

September 19, 2014 - Vacuum Interrupters, Inc. is proud to introduce its new rigid magnetic coil for the MAC-TS4 vacuum interrupter tester, or test set, which allows technicians to test vacuum interrupters in GE PowerVac breakers in place without disassembling.

Using the Penning discharge principle, the MAC-TS4 vacuum interrupter tester, or test set, can determine the pressure inside a vacuum interrupter and this, along with wear, age and number of operations, predicts the usable life of the vacuum interrupters used in your circuit breakers and contactors.

Used in conjunction with the MAC-TS4 test set, the PowerVac rigid magnetic field coil slides over the PowerVac pole assembly, allowing the technician to determine the interrupter’s remaining lifespan without removing the vacuum interrupter. The MAC-TS4 and rigid coils reduce the downtime required to test vacuum interrupters in the field and help prevent unnecessary damage to your circuit breakers and contactors by identifying impending failures before they happen.

This easy-to-use portable PowerVac rigid coil is the first of many breaker-specific coils currently being developed by Vacuum Interrupters, Inc.
