DEHNguard modular with Advanced Circuit Interruption (Safe Dimensioning)

  • New technology ""Advanced Circuit Interruption"" (ACI) integrated in the protection module, consists of a switch / spark gap combination
  • Due to ACI technology no external backup fuse required
  • Small connection cross-sections (6 mm² Cu) absolutely sufficient *)
  • TOV withstand also at 440 V (AC)
  • High system reliability, no tripping of 32 A gG fuses
  • Zero leakage current due to galvanic isolation by ACI switch unit
  • Energy coordination with other arresters of the Red/Line product family
  • Vibration and shock-tested according to EN 60068-2
  • Push-in connection system

*) All live conductors should be wired so that they are inherently short-circuit and earth fault proof
