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.
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).
Two layers change-over switches MS series types CO4-5-6 from 630A to 3150A, power multiple power supply voltage 24V DC, 110/220 AC, visualisation by digital display and mechanical indicator.
