Starting adjustment resistor RQ56-355M-10/18

OneLifting resistorMain technical parameters:

This resistor is mainly used as a universal resistor for matching the S3, S4, and S6 working cycles of YZR series motors in crane equipment. It is suitable for use as a starting, adjusting, and braking resistor for motors in circuits with AC voltage ranging from 50Hz to 660V.
Match the resistor model for YZR series motors.
