ATK-IFLS616 / IFLS617 Residual Current Fault Monitor

From circuit monitoring to fault-waveform analysis

ATK-IFLS616 and IFLS617 identify the same product for zero-sequence current monitoring in IT and TN systems, with a 0–70 mA measurement range and 0–1000 Hz monitoring frequency. The supporting communications and software provide 100 ms polling, system monitoring of more than 50 circuits, waveform recording and Fourier analysis. The multicircuit capability belongs to the networked system, not the terminal count of an individual device.
