Line test resistor

The Line test resistor checks whether a short circuit occurs to protect more valuable components as the High-Speed DC circuit breakers against wear and tear and excessive current flow.

Thanks to our design and manufacturing skills, the resistor can ensure low-temperature operation in HSCB trolley installations. In outdoor applications, the resistor can support harsh conditions and dissipate high energy up to 20 MJ.

  • High Energy absorption or repetitive duty cycles
  • Light and compact solution for HSCB trolley installation
  • Robust and low maintenance for outdoor installation
  • Low ohmic variation range
  • Low inductance value
