OEM Replacement Vacuum Interrupters
Replacement vacuum interrupters (vacuum bottles) for medium voltage circuit breakers and contactors. OEM and aftermarket options with predictive testing to identify bottles before failure.
Vacuum Interrupter Solutions
Vacuum interrupters are the heart of medium voltage vacuum circuit breakers and contactors. Over time, vacuum integrity can degrade — and traditional high-potential (HiPot) testing can miss bad interrupters, giving false negative results.
Predictive magnetron atmospheric condition (MAC) testing provides a more reliable assessment of vacuum interrupter condition than conventional HiPot tests. Call 800-232-5809 to ask about predictive testing.
