Product information "IKI-35_24V"

Current transformer supplied protection relay

  • Application as transformer protection
  • Availabe with wide range converters
  • Overcurrent, short-circuit, and earth fault stage
  • Intuitive operation thanks to menu navigation
  • Inrush suppression
  • Event memory
  • Earth fault protection by balance current transformer or calculation from the phase current transformers possible

Trigger characteristics  

  • DMT I> (ANSI 51)
  • IDMT I>, four characteristic curves (ANSI 51)
  • 2 short-circuit levels I>>, I>>> (ANSI 50)
  • External quick-trigger
  • Earth fault level DMT or IDMT Ie> (ANSI 51N or 51G)
  • Instant earth fault level Ie>> (ANSI 50N or 50G)

Magnetic trigger selectable

  • Low-energy triger,0.02 Ws, without external power supply
  • Low-energy trigger,24 V/0.1 Ws, without external power supply
  • Standard trigger coil (with additional external capacitor storage PSU)

Self-test function

Event memory

  • for 20 events, availabe for download with mini USB cable via software (PC)

Low-maintenance due to transformer power supply

  • Internal battery life > 15 years without transformer current
