The three and four pole change-over switches, with motorized operation,
allow remote control of change-over/breaking/disconnection under load
of power circuits in low voltage systems.
The range of motorized change-over switches is made by 15 sizes of
switches of current rating from 160A to 4000A, 3 and 4 poles are
available in the CS series with switch disconnectors laid one upon the
other and in the “CO” series with switch disconnectors horizontally
The CS series is made by 4 families: MSX, MSX1, MSY, MS differentiated
between them mainly by the supply voltage and by the display of the
position of the change-over switch.
The horizontal CO series is made in the MS version only.
