When selecting the motor protector functions, it's essential to consider the motor's operating parameters and failure causes from multiple dimensions, and truly understand what functional requirements are necessary to protect the motor. Selecting functions is a basic requirement for protecting parameters, but understanding a motor's performance is not something that can be mastered overnight: I'll give an example:OverloadOvercurrentProtection:During monitoring the three-phase current values, if any phase or the average current of all three phases exceeds the set overcurrent value, the screen will display "Overcurrent" and prompt the actual phase overload current value, with a blinking alert.Overload Protection AlertSet trip circuitTime isInner，EquipmentRelayTrip circuit breakerMotionOutput; but this is how you can withdraw the cash: each motor protector has a settableTrip circuit operation time1s~255sIf the preset operating current exceeds the overload current setting,Separately listedSetTrip circuit breakerTime1s or250sAt the moment, you can view the actual protection action relay output of the protector.。
