The IEC 644 applies to fuse contacts used on alternating current systems with engines started direct-on-line. Medium voltage fuses used in engine circuits must be able to withstand the repeated fluctuations associated with the start of the engine without breakdown. In cases where fuses have to be parallel, special connection elements can be delivered.


  • Dielectric losses are very small
  • Higher current carrying capacity
  • Light in weight
