MPR300 series intelligent motor protection controller

Product Introduction

The MPR300 series intelligent motor protection controller is mainly used to operate the contactor in the control circuit of AC motors with AC 50Hz or 60Hz, rated insulation voltage up to 690V, and rated current up to 820A. It protects the motor in the event of overheating, overload, locked rotor, undercurrent, phase loss imbalance, grounding, leakage, undervoltage, overvoltage and other faults. At the same time, it realizes functions such as measurement, display, control, protection, transmission and communication, helping customers to comprehensively analyze and manage the operation of the motor to improve the reliability and efficiency of power supply.
