Development of  proprietary materials, innovative contact designs and new manufacturing techniques 

have enabled us to continuously reduce the size of vacuum interrupters to facilitate smaller and more

efficient product designs.

 

Our vacuum interrupters are available in several designs and for multitude of switching applications.

We offer compliance to ANSI, IEC, GB and JIS  standards.
