Rated 6 A with a C-curve trip characteristic and 10 kA breaking capacity at 230...240 V AC, it protects a single-phase final subcircuit against overload, short-circuit, and earth leakage (300 mA sensitivity) in one package. The thermal-magnetic trip unit handles the overcurrent side; the integrated earth-leakage module covers the ground-fault protection.
The 6 A rating limits the continuous load to lighting or small socket circuits; the C-curve (magnetic trip at 5-10 x In, so 30-60 A instantaneous) suits moderate inrush loads like fluorescent banks or small motors. The 300 mA earth-leakage sensitivity is a delayed or high-threshold residual-current setting — not a 30 mA personal-protection level. It is intended for equipment protection or fire-prevention on circuits where nuisance tripping from leakage in permanently connected equipment (water heaters, computers, HVAC) would be unacceptable. The integrated RCD module means no separate earth-leakage device is needed in the same DIN-rail row, saving one module width.
IP20 finger-safe terminals (IP40 inside the modular enclosure) suit enclosed distribution boards; not rated for wet or dusty environments. The toggle gives local ON/OFF/fault-trip indication, useful for troubleshooting without a meter.
