Overview

The motor protection controller WDH-31-200 is used for the protection of low-voltage AC asynchronous motors, and can replace electrical components such as thermal relays, time relays, and transmitters. Its protection range is wide, and its precision action is precise and reliable. When a fault occurs, the troubleshooting is more intuitive, which can help customers quickly determine the cause of the fault and reduce economic losses.
