K8AK-PH

Funksjoner

Relé for trefaset faseretning og fasefeil

Overvåkingsreleet K8AB-PH1 er utformet for overvåking av trefaset forsyning med tre ledere. Det overvåker faseretning og fasefeil samtidig under oppstart, samt fasefeil under drift. Utgangsreleet utløses hvis det oppdages alarmforhold, og varselstatusen kan enkelt overvåkes ved hjelp av LED-indikatoren. Passer for industrianlegg og -utstyr.

  • Overvåker faseretning og fasefeil samtidig
  • Måleområde: 200 til 480 VAC
  • Forsyningsspenningen er den samme som målespenningen
  • Reaksjonstid: maks 0,1 sek
