K8AK-AW

Kenmerken

Eenfasig stroomrelais, 'window'-type

Deze eenfasige stroomrelais bewaakt over- en onderstroom. Handmatig resetten en automatisch resetten worden door één relais ondersteund. De startblokkering en schakeltijd kunnen apart worden ingesteld. De waarschuwingsstatus van het relais is eenvoudig te bewaken met de LED-indicator.
  • Eenfasig stroomrelais, 'window'-type
  • In industriële behuizing van 22,5 mm breed
  • Onder- en overbesturing
  • Voedingsspanning: 24 VAC/VDC, 100 tot 240 VAC
  • Eenvoudige bedrading met behulp van adereindhulzen
