It combines a C-characteristic miniature circuit breaker and a Type A residual current device (30 mA) in one DIN-rail module, saving panel space compared to a separate MCB + RCCD pair.
The 1P+N form factor occupies a single modular width on a DIN rail, with the neutral pole switched internally. The C-characteristic curve trips at 5–10× In, suited for circuits with moderate inrush, such as motorized appliances or capacitor banks.
