6.2.5 Vacuum contactor - type V-Contact

The V-Contact type vacuum contactor is ideal for controlling users in a.c. requiring a high number of
operations. The contactors basically consist of a moulded resin monobloc, where the vacuum
interrupters, moving apparatus, control electromagnet, multivoltage control feeder and auxiliary
accessories are housed.
The monobloc is also the support for assembly of the fuse-holder frame.
Closing of the main contacts is carried out by means of the control electromagnet. Opening is carried
out by means of a special opposing spring. The contactor can be equipped with electrical or mechanical
latching.
The fuses are positioned in special supports to be connected in series between the contactor and the
user. The supports can house fuses in compliance with DIN or BS standards.
For details, please refer to installation manual.
