Hrc Fuse Link,knife contactor NT4 fuse link 1250A 600V Model: NT00C, NT00, NT1, NT0, NT1, NT2, NT3, NT4.  NT3 fuse link  1250A 600VModel:  NT00C, NT00, NT1, NT0, NT1, NT2, NT3, NT4. NH00C, NH00, NH1, NH0, NH1, NH2This series of fuse link are used in AC 50HZ ,rated voltage up to 690V,rated current up to 1250 A and  for protecting electric equipment from overload and short-circuit. It can reliably break the min. fusion current to any current within 120KA.

It also available for the protection of semiconductor parts and equipment against short-circuit (type aR) and protection of motors (type aM).
