It is rated Icn 6 kA, Type A sensitivity at 30 mA, C-characteristic tripping curve, rated current In 20 A, and rated voltage Un AC 230 V.
Type A residual current detection handles pulsating DC fault currents (typical from rectified loads like washing machines, LED drivers, or single-phase VFDs) in addition to sinusoidal AC. The 30 mA sensitivity provides additional protection against direct contact hazards per IEC 60364. C-curve (C-Char) means the magnetic trip operates at 5 to 10 times In (100–200 A for this 20 A unit), suited for circuits with moderate inrush — lighting banks, small motor loads, or capacitor switching — where a B-curve would nuisance-trip.
