K8AK-AS

Funksjoner

Enfaset strømrelé

Disse enfasede strømreleene overvåker over- og understrøm. Manuell tilbakestilling og automatisk tilbakestilling støttes av ett relé. Oppstartslås og driftstid kan stilles inn separat. Reléadvarselsstatus kan lett overvåkes med LED-indikatoren.
  • Enfaset strømrelé
  • I 22,5 mm bred kapsling
  • Under- eller overkontroll
  • Forsyningsspenning: 24 VAC/DC, 100 til 240 VAC
  • Enkel tilkobling med hylser
