Q What's the differences between the TF,TD,TC and TJC?
A The vacuum interrupters are applied in different switchgears. "TF"means it applies to load-break switch; "TD" means it applies to circuit breaker; "TC" means it applies to recloser; "TJC" means it applies to contactor.

Q Can I apply the vacuum interrupters in the high altitude areas?
A Vacuum interrupters can be applied in high altitude areas,but you should confirm if the withstand voltage meet the requirement.
-
Q What's the contact structure of the vacuum interrupters for VCB?
A There are AMF(Axial Magnetic Field) and TMF(Transvers Magnetic Field) structure for the contact.There's no much difference between the two structure at the rated short-circuit breaking current below 12kV 31.5kA. However, AMF structure performaces better and gets longer life over 40kA.

Q How to choose the embedded pole?
A Apart of the technical parametre of the embedded pole，it's very important to confirm the size of mounting base and the height to the terminal.
