Product description
RCI reversing contactors are designed for demanding forward/reverse control of 3-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
Conveyors, thread cutting machines, packaging lines and other applications where fast reversing capabilities are needed.
