Cylindrical equipment fuse-links for DC circuits up to 1500 V DC, intended to protect converters supplying air-conditioning systems and passenger electronics.

Quartz filling immediately extinguishes the DC arc plasma, limiting the energy passing through the protected circuits. Reduced thermal losses due to low internal resistance limit heating of enclosed underframe boxes - particularly important where forced ventilation is not available.

Key features:

  • DC circuits up to 1500 V DC
  • Quartz filling extinguishes DC arc plasma and limits energy passing through the protected circuit
  • Reduced thermal losses from internal resistance
  • Installation in enclosed underframe boxes without forced ventilation
