1. VITZROTECH VC & VCS INTRODUCE (Vacuum Contactor Switches)
● VITZRO TECH Vacuum Contactor Switch is a miniature, high-performance MV VCS.
It is highly reliable and stable and easy to use. There are 2 types of fixed excitation mode
and instantaneous excitation mode that do not require maintenance. It is a switch for
medium voltage motor, transformer and condenser circuits and it contributed greatly to
the modernization and simplification of the equipment.
● Its performance was recognized through technology integration and international
- It is a product with the maximum short circuit capacity conforming to the international standard IEC-
● It improves the safety by applying an excellent breaking capability and a long-term
- The arc time at all areas of current is generally 0.5 cycle or below.
It performs a great breaking capability during the opening and closing of condenser bank. The
chopped current is less than 1(A) so when interrupting the load current of motor and the exciting
current of transformer, a high surge voltage is not generated.
- The mechanical life cycle of fixed excitation mode is 2,500,000 times and that of instantaneous mode
is 250,000 times. The electrical life cycle is 250,000 times of the load opening and closing.
● It is easy and safe to use with various optional functions.
- There are 4 types of ratings - fixed type, individual draw-out type, draw-out type (standard draw-out
type and external draw-out type) and mechanical interlock mounting type - with total of 36 product
types. All draw-out types are mounted with a draw-out unit. However, a power fuse is mounted when
● There is enough space due to its compact size and light-weight.
- It is possible to mount a distribution panel with 600 mm width and it can be loaded in 3 columns.
