The PR series motor protection relay is used to monitor the motor to protect the motor. These motor protection devices integrate monitoring, control, protection, communication, and other functions, and can provide various protections for the motor. When the motor has overcurrent, undercurrent, phase failure, overvoltage, under voltage, and three-phase inequality, the digital motor protection relay will give an alarm or protection control. In almost all applications, including pumping, air-based, chiller, and bulk material applications, it provides low-voltage motor protection.
We can provide various types of motor protection relays, with functions ranging from simple to complex. All our products are three-phase motor protection relays with high quality and competitive prices. To know more about the differences in our electronic motor protection relay, please contact us directly.
