1、Overview:

The three-phase four wire overvoltage and undervoltagecurrent limiting protector is currently available in themarketA new generation of home appliance protectiondevice developed by the Electric Condition Institute.Control line selectionAssembled withimportedcomponents,produced using modular standards forproduct performanceExcellent andreliable.Can bepositive in case of abnormal voltage, current, and phasesequenceWork regularly.When the voltage and current ofthe mains exceedthe action threshold of theprotectorWhen the phase sequence is disordered and thevoltage and current are unbalanced,the protector canquicklyReliably cut off the circuit to protect electricalequipment and personal safety.When the mains voltagereturns to normal, the protector can automatically connectto the power supplyRestore power supply, automaticallyimplement local functions without the need for personnel

2、Main functions:

1.Overvoltage protection,undervoltage protection.overload protection,undercurrent protection,delayprotection,voltage imbalance protection,currentimbalance protection,phase loss protection,phasesequence protection,leakage protection, each parametercan be set with action threshold and on/off.
