Product information "IKI-Overhead Butler"

Error detection of all typical overhead line faults

  • Short circuits, transients and earth defects

Ultra bright LED indicator

  • Visibility cone 360°, visible even in bright sunlight

Easy installation by means of actuating rod

  • The built-in torque indicator indicates the correct installation. No additional tools required.

Reliable fault detection

  • By independent current/time characteristic (UMZ); Short circuit and earth fault detection; Detection of high-impedance errors by dI/dT/dT capture; Inrush suppression; Fault confirmation by monitoring for shutdown via integrated voltage sensor

Simple setting of parameters by DIP switches

  • Response current (automatic or fixed thresholds 200 - 600 A).
  • Reset time (2 - 8 h, manually or automatically after load current return). Access to DIP switches without tools possible.    

Long service life

  •  Through high-quality lithium battery, nanowatt technology and corrosion-free housing.
