All the contactors mentioned above are available, on request, in one

of the two following versions.

– SCO (Single Command Operated): closing takes place by supplying

auxiliary power to the special input of the multi-voltage feeder. On

the other hand, opening takes place when the auxiliary power is

either voluntarily cut off (by means of a command) or involuntarily

(for lack of auxiliary power in the installation).

– DCO (Double Command Operated): closing takes place by

supplying the input of the closing command of the apparatus in

an impulsive way. On the other hand, opening takes place when

the input of the opening command of the contactor is supplied

in an impulsive way.

Fields of application

The V-Contact VSC contactors are suitable for controlling electrical

apparatus in industry, in the service sector, in the marine sector, etc.

Thanks to the breaking technique with vacuum interrupters, they

can operate in particularly difficult environments.

They are suitable for control and protection of motors, transformers,

power factor correction banks, switching systems, etc. Fitted with

suitable fuses, they can be used in circuits with fault levels up to

1000 MVA (VSC7 – VSC12).
