Technical Specification
  • ot/operating trip delay time :0.1~60sec
  • dt/starting delay time :0.1~60sec
  • Primary rating of external shunt:1/3/5/10/15/20/30/40/50/75/100/125/150/200/250/300/400/500
    • The preset value of ”oc”and “uc” is naturally changed as follows:
      • "oc” becomes the rating of shunt
      • ”uc” becomes “oFF”
  • Current range of external shunt, each
    • 10A : 1A~10A , 15A :1.5A~15A
    • 20A : 2A~20A , 30A : 3A~30A
    • 40A : 4A~40A , 50A : 5A~50A
    • 60A : 6A~60A , 75A : 7.5A~75A
    • 100A: 10A~100A , 125A: 12.5A~125A
    • 150A: 15A~150A ,200A: 20A~250A
    • 250A: 25A~250A ,300A:30A~300A
    • 400A:40A~400A ,500A : 50A~500A
  • automatic reset target :this function is executed in case “Aut” is preset in “rSt”(“rESEt) mode
    • ALL : for both OC and UC
    • OC : only for OC
    • UC : only for UC
