What is a cold water machine open phase protection

High power machinery motor adopts three-phase power supply of cold water. Normal voltage is 208 v, 230 v, 460 v, 575 v. Some special equipment also USES a higher voltage, such as 4160 v or 13000 v. No matter how much voltage, all must have a complete three-phase circuit, or cold water machine the motor will be immediately overload. Electronic phase protector to regular monitoring of the power supply, ensure the automatic stop when appear defect status.
