The marine electromagnetic starter is suitable for controlling the direct start, stop, forward and reverse operation of three-phase AC380V and 50HZ three-phase asynchronous motors, and implements overload, short circuit, voltage loss and lack of phase protection for the controlled motor and related circuits. The box body of the starter is cold-rolled plate, and the protection grades are IP22 and IP44. The QC series has two forms, QC91 and QCC1. The control principle is basically the same. The difference is that the control loop voltage of QC91 is AC380V, and the control loop voltage of QCC1 is AC220V.
