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.
COMPOSITION OF THE RANGE
The range of motorized change-over switches is made by 14 sizes of switches of current rating from 160A to 3150A, 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 interlocked.
The CS series is made by 4 families:
MS, MSX, MSX1, MSY, 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.
GENERAL CHARACTERISTICS
The motorized change-over switches are made by means of two switch disconnectors of “Visualcompact” series mechanically interlocked.
• Automatic under-load change-over (AC22, AC23) from and to any of positions “1”, “0”, “2” both electrical and manual (emergency change-over), transfer function with direct transition from position “1” to position “2” and viceversa.
• Front display of positions “1”, “0”, “2” by digital display and/or mechanical indicator (for MS version).
• Safety: locking by padlock preventing any electrical or manual operation, key lock for the selection of electrical or manual operation (on MS series only).
• External signalisation of positions “1”, “0” and “2” by a clean contact (no voltage supply).
• Quick operating time from pos. “1” to “2” and viceversa (see tables at pages 144 and 145).
• Easy and fast electrical connections by means of terminal blocks of quick connection type.
• Power supply voltage 12-24V DC, 110/220/380V AC, others on request.
• Compact dimensions
• Selection of operating logic by a micro switch on the PC board and easily accessible for the following logic:
• a. impulse (150 ms min)
• b. contactor (maintained contact).
