    2. Accord to pole:3P、4P
    3. Accord to operation:Electric operation,Manual operation(Repair,maintenance)


    Intelligence controller,under-voltage instant(or delayed)release,shunt release.

    Intelligence controller function:

    1. intelligence controller:H(intelligence type),M(Standard type)、L(Economy type)
    2. Have overload long delayed inverse time limit,short delayed inverse time limit,constant time-lag and instant function,it can according to user require to set protect.
    3. Single ground protect function.
    4. Display function:setting current display,action current display and each line voltage main display(voltage display need ask us when give me the order)
    5. Alarm function:overload alarm.
    6. Self test function:overheating self test,microcomputer self diagnosis.
    7. Test function:intelligent controller of operating characteristic.

    Normal use and installation condition

    1. Ambient air temperature:upper limit value not exceeding+40℃,lower limiting value not exceeding -5℃,average value not exceeding +35℃.Special orders expected.
    2. Install address of altitude not exceeding 2000m.
    3. Atmospheric conditions:Atmosphere relative humidity not exceeding 50% when ambient air is +40℃,it can have higher of relative humidity in the lower temperature ,the average max relative humidity is 90% in the max wet month,this month average max temperature is +25℃ at the same time ,it need to think about condensation of product’s surface which will a[[ear with the change of temperature.It need consult with my company when it exceed regulated requirements.
