It carries a C-curve 10A overcurrent trip and a 300mA Type AC earth-leakage trip, with a 10kA breaking capacity. The 70mm depth fits standard distribution boards.
The 10A C-curve means it handles lighting, socket outlets, and small motor circuits where inrush current is moderate — the C-curve trips at 5–10× rated current, so it won't nuisance-trip on a motor start or capacitor bank. This is a common choice for general-purpose circuits where pulsed or DC fault currents aren't expected — think office lighting, general socket circuits, or heating loads.
The 1+N-pole format (switched line plus switched neutral) is common in UK and European installations where the neutral is broken with the phase. The 70mm depth is a standard module width — it occupies one 18mm pole position plus the neutral pole, so it takes two module widths on the rail. Wire it with the line and neutral incoming at the top, load out the bottom; the neutral is switched internally, so no separate neutral bar is needed for the protected circuit.
