  • Standard single chip structure, pluggable
  • Consist of varistor and thermal disconnection device
  • High discharge capacity, quick response
  • Double thermal disconnection devices,
  • provide more relible protection
  • Multifunctional terminals for connection of conductors and busbars
  • Green window will change when fauit occurs,
  • also provide remote alarm terminal at the same time
