What this RCBO does for a panel
The 4.5 kA breaking capacity at 230–240 V AC, 50 Hz, per EN/IEC 61009-2-1, is sized for residential and light commercial outgoing circuits where the prospective fault current stays under that threshold.
The 300 mA earth-leakage sensitivity is a common choice for general-purpose socket-outlet circuits where 30 mA would trip on normal cable leakage; it protects against insulation faults but allows for longer cable runs.
Terminals accept 1–16 mm² rigid or 1–10 mm² flexible wire; strip length is 15 mm, tighten to 2 N·m.
