CI-tronic™ Reversing contactor
Type RCI
RCI reversing contactors are designed for
demanding forward/reverse control of
three-phase AC motors. The zero cross
switching method ensures very fast and precise
motor control and virtually eliminates EMC
emission. The RCI reversing contactor is ideal
where fast switching capability and long life are
essential. Typical applications are conveyors,
thread cutting machines, packaging lines and
other applications where fast reversing
capabilities are needed.

When control circuit A1 – A2 is ON, the motor will
rotate forward. With control circuit A3 – A4 ON
the motor will rotate in reverse direction. If both
control circuits are switched ON the motor will
rotate in the direction determined by the circuit
which was switched ON first. A delay time
(interlock) between forward and reverse running
is incorporated.
