15 modelsVacuum Interrupter for Circuit Breaker
GLVAC TD Series circuit breaker vacuum interrupter tubes — OEM components providing superior arc suppression and long electrical life for medium-voltage (MV) power distribution and industrial system circuit breakers. 15 models, 1.14-40.5 kV (6 voltage classes), 400-2000 A rated current, 8-31.5 kA rated breaking current. Designed for maintenance-free performance.
5 modelsVacuum Interrupter for Isolating Switch
GLVAC TF Series isolating switch vacuum interrupter tubes — core components of medium-voltage isolating switches (disconnect switches) and load break switches. 5 models, 7.2-40.5 kV (4 voltage classes), 200-1250 A rated current, 10-25 kA short-time withstand. 10,000 to 50,000 mechanical cycles — for frequent-operation load break applications.
6 modelsVacuum Interrupter for Tap Changer
GLVAC TJ Series tap changer vacuum interrupter tubes — vacuum interrupters specially designed for On-Load Tap Changer (OLTC) operation in power transformers. 6 models, 1.14-12 kV, 80-600 A rated current. 1 million mechanical cycle life provides extended service intervals and reduced arcing.
24 modelsVacuum Interrupter for AC Contactor
GLVAC TJ Series AC contactor vacuum interrupter tubes — high-performance core components of AC vacuum contactors that rapidly extinguish arcs and suppress current using high vacuum insulation inside the tube. 24 models across 5 voltage classes (1.14 kV to 12 kV), rated current from 125A to 2500A. OEM components for AC contactor manufacturers.
