It combines overcurrent protection (C-curve, 6 A rated at 30 °C) with residual current detection (30 mA, Type A) in a single 2-module-wide unit. That means one device handles both thermal-magnetic trip for overloads and short-circuits, and ground-fault interruption for sinusoidal AC and pulsating DC residual currents.
C-curve characteristic means the magnetic trip fires at 5 to 10 times In (30–60 A for this 6 A unit), suited for mixed resistive and moderate inductive loads like lighting circuits, small motors, and control transformers. The 30 mA residual sensitivity is the standard for personal protection against fatal shock in most IEC-based codes. Type A detection covers both pure AC fault currents and pulsating DC — the kind you get from single-phase rectifiers in electronics or LED drivers. The 4 kV rated surge voltage (impulse withstand) means it survives switching transients and nearby lightning-induced spikes without nuisance tripping or damage.
