Pickup (calculated ground current)
±1.5% of the setting value or 1% In
±2.0% of the setting value or 1.5% In
Dropout Ratio 97% or 0.5% In
t DEFT
±1% or ±10 ms
Operating Time
At testing IE ≥ 2 times pickup value
<20 ms
Disengaging Time <38 ms
t-reset (Reset Mode = t-delay) ±1% or ±10 ms

For earth current sensitive the precision does not depend on the nominal value
but is referenced to 100 mA (with In = 1 A) respectively 500 mA (with In = 5 A)
