MotorProtectiveRelay1

詳細(xì)介紹

 

   
 
   Motor Protective Relay  
 


 
 

1. Protection for 3 phase motor with certain in any cases: over load, single phase operating, reverse, even earth fault.
2. Wide range of current setting and time setting in one unit.
3. Input circuit is equipped with “surge" protection circuit for no error.
4. Built in semiconductor H-IC circuit : And strong against shock and vibration.
5. D4E type protects motor from earth fault with ZCT.
