MV Vacuum Contactors
MV Vacuum Contactors Supplier
MV Vacuum Contactors
EPCOS offers state of art Vacuum Contactors for various applications. Vacuum contactors have an edge 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
Product Description
