The MRC reverse starter enables the operation of
asynchronous motors with a reverse function. A
mechanically locked reversing contactor as well as a
braking contactor are integrated in the device. The
motors are protected against short circuits by an overload
monitoring function. The motor starter itself is protected
by internal fuses that cannot be replaced.
