Product information "IKI-Overhead R2"

With the IKI-Overhead R2, overhead lines can be easily monitored for faults and thus integrated into the overall protection concept to minimize downtime. Fault indication is provided locally via strong LEDs.

Fault detection of all typical overhead line faults

Short circuits, transients and ground faults

Ultra-bright LED display

Visibility cone 360°, visible even in bright sunlight

Easy installation using actuating rod

Integrated torque indicator shows correct installation. No additional tools required.

Reliable fault detection

Overcurrent and short-circuit via to independent current/time characteristic; short and earth (short) circuit detection; high impedance fault detection by dI/dT detection; inrush suppression; fault confirmation by monitoring for disconnection via integrated voltage sensor

Simple parameter setting by DIP switch

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

Long life

due to high quality lithium battery, nanowatt technology and corrosion-free housing.

Easy installation

Torque indicator for safe mounting
