умный защиты электродвигателя

JDD Series GENERA In modern industrial production,the motor is mainly damaged due to phase failure,overload,over-voltage or locked rotor,On the basis of the working prinple of the three-phase AC motor as well as analysis on the main causes of motor damage,we developed the intelligent motor protector that can be applied to three-phase circuity, protect the circuity against the overload,long service life,etc,It adopts the solid digtial window in apperance design ,which can clearly show whether the equipmentis in normal state,it ranks the advanced level in the similar industries. MAIN FUNTIONS Protection funtions: against overload,phase failture,locked rotor,three-phase current unbalance,under-voltage,etcFault display:working power indication of phase A,B,C(the indicator lamp would go out when any one phase is failture),overload indication(when the motor`s working power of motor would be out off)If above mentioned fault occurs ,the stop indicator lamp would go on ,and the working power of motor would be cut off.Setting funtion: it is able the rated current and over-current protection delay time on site.
