80a three phase voltage current protective energy meter  
voltage protector


Products Description


  WST238-7 VAP type multi-function Protective Device is designed to measure three phase four wire 

AC active energy / reactive and used in overvoltage protection, under voltage protection and over-

current protection. In case of over-voltage fault, under-voltage fault or over-current fault in line, this 

product can instantly power off the load to prevent electrical equipment from being burnt. The over-

voltage, under-voltage and over-current values of this product can all be set up by yourself and can 

be adjusted on the basis of local practical condition .It is a long use-life product with the advantage 

of high stability , high over load capability , low power loss and wide working voltage range.


Functioning


■LCD display with backlight , can display total active energy (kWh), total reactive energy (kvarh),

  three phase real time current(A), voltage(V), active power (KW),reactive power (kvar) .power

  factor ,frequency

■LCD display kWh (6 digital+2 decimal), Bi-directional total active energy measurement reverse

  active energy measure in the total active energy

■Product self-design has function of lighting protection

■Overvoltage protection, under voltage protection and over-current protection and lose phase

  protection can select auto-Reclosing mode or manual--Reclosing mode

■In case of over-voltage fault, under-voltage fault or over current fault, lose phase in any phase line,

  the product can power off the line and can automatically restore connecting the line over a time

  delay after voltage of the lien is recovered to normal condition.

■In case of transient over voltage in line, the product can protect the equipment from false operation.

■In case that the line subjects to unstable voltage or sudden power-off and power-on due to

  loosened connection and other fault, the product will disconnect the line.

■When fault voltage of the line reaches the peak, the product itself will not be damaged.

■Lose neutral line protection

■Lose phase protection ,and there have phase led indication on meter

■Unbalance voltage protection , if the voltage unbalance value exceed the setting value between

  any 2 phase of three phase .the device will cut off the load

■Over-current protection mode

■It can setting delay time for delay switch on / switch off function

■Interval active energy measure , it can resettable in any time after push button last 5s

■Last 5 times protection event records

■Diversified design for the protection , you can closed t any one of overvoltage protection, under

  voltage protection and over-current protection in any time

■35mm din rail installation , bottom type wire connection
