K8DT-PM

Funktioner

3-faset spændings- og fasefølge-, fasebrudsrelæ

Beskytter motorer og andet udstyr mod ustabile spændinger i strømforsyningssystemet. Beskytter motorer og andet udstyr ved registrering af overspændinger, underspændinger, fasefølge og faseudfald for trefasede strømforsyninger.

  • Registrering af faseudfald, mens motoren er i drift
  • Gælder i stort omfang for 3-faset, 3-leder system (ændret med en DIP-switch)
  • Større modstand over for frekvensomformerstøj
  • Bredde på 17,5 mm mhp. reduktion af påkrævet plads i tavler
  • Push-in plus-teknologi, som reducerer fortrådningen
  • UL-registreret for nem levering til Nordamerika
  • Dobbelte indsætningshuller til ledningsoverføring (alle klemmer)
  • Modeller forsynet med transistorudgange mhp. uovertruffen kontaktpålidelighed
  • RoHS kompatibel
