Overhead fault circuit indicator FCI-AR

 Indicado-de-fallas ok  


The fault circuit indicator manufactured by CELSA is an automatic device for installation in overhead distribution lines, to monitor the current and voltage parameters in order to detect faults where it is installed.



Operating trip modes







·Auto adjustable


Programming features

The FCI has a data communication interface to set its functional parameters, and query stored statistics data, Firmware updates among others. This procedure can be performed using the SIGMA software with a computer and the proper interface.


Manual restore and device test

The normal operational mode can be checked by the use of a magnet, placing it close to the TEST label (the LEDs should flash). Additionally, the FCI can be manually restored.



The visual indication of a fault, is made by bright LEDS, RED for permanent faults and AMBER for temporary faults.




Power supply 

The FCI uses long life lithium batteries (more than 10 years, storage conditions). They can be easily replace by the user.



The FCI’s has a circular memory to store date and time for each fault, the total amount of temporary and permanent faults, and other events like line’s circulating current.
