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.
