MV Vacuum Capacitors

MV Vacuum Capacitors

EPCOS offers wide range of Vacuum contactors for various applications. Vacuum contactors have an age over gas / air / oil type switches because of highest dielectric strength of vacuum. Vacuum contactors use state of art vacuum interrupters selected to perform the required duty. Vacuum contactors are used for lower current breaking e.g. motor current, capacitive current and other low inductive currents.
