Arc fault protective system ARCON^® [t-head1-pg]

Maximum personnel and system safety, especially during continuous production processes, made possible using the arc-fault protective system ARCON. The system offers protection from 6 to 100 kA_rms arc fault current.

Detection of the arc faults is by light and current sensors. The evaluation unit responds when light and current signals are present. A tripping signal is applied to the quenching device and to the feeder circuit-breakers. The fault arc is quenched in less than 2 ms. The system can be put back into operation as soon as the fault is eliminated and the quenching device is renewed.

Things happen extremely quickly once the electronic evaluation unit has responded. ARCON^® has quenched the fault arc in 2 ms, before it can cause serious damage.
