J7TKN

Funktioner

Termorelæer til J7-kontaktorer

J7TKN relæer beskytter motorer mod termisk overbelastning. De kan monteres på kontaktoren eller separat. Relæerne overholder IEC 947 (enkeltfaset følsomhed).

  • Serie af termorelæer, der dækker et indstillingsområde fra 0,24A til 220A
  • Alle komponenter har fingerbeskyttelse
