Vacuum Contactors

The vacuum contactors from Schrack Technik are the ideal alternative to conventional air contactors – special circumstances need special contactors.

Vacuum Contactors - LSD Contactors

There are basically two types of contactors, air contactors and vacuum contactors. In air contactors it is possible for sparks to be generated during switching. The special design of vacuum contactors prevents any sparks. The switching contacts in vacuum contactors are contained in an evacuated switching tube – it is impossible for sparks to form and the contacts cannot be incinerated – and the service life is virtually unlimited.


Schrack Technik offers vacuum contactors of the sizes 6/10/12/14. Please contact us for vacuum contactors in other sizes.
