IKI-Overhead Butler
Fault indicators for overhead lines,
on-site display via LEDs,
close-range radio for querying up to 8 IKI overhead radio
Part-No.: 2501306
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.
