Functions
and characteristics
By combining a remote-operated source-changeover
system with an integrated BA
or UA automatic controller, it is possible to
automatically control source transfer according to user-
selected sequences.
These controllers can be used on source-changeover
systems comprising 2 circuit breakers.
For source-changeover systems comprising 3 circuit
breakers, the automatic control diagram must be
prepared by the installer as a complement to to
diagrams provided in the “electrical diagrams” section
of this catalogue.

(1) For example, 220 V single-phase or 220 V three-phase.
(2) The controller is powered by the ACP auxiliaries control plate. The same voltage must be used
for the ACP plate, the IVE unit and the circuit-breaker operating mechanisms. If this voltage is the
same as the source voltage, then the “Normal” and “Replacement” sources can be used directly
for the power supply. If not, an isolation transformer must be used.
