Rated 3 A at 240 V AC, 50 Hz, with a C tripping characteristic, it is sized for moderate inrush loads like small motor starters or lighting banks where the C-curve holds off transient surges up to 5–10 times rated current before tripping. Overvoltage category 3 and energy limiting class 3 align with standard distribution board duty — it limits let-through energy during a fault, protecting downstream wiring and connected equipment.
The 1P+N format means the neutral is switched internally — no need for a separate neutral link, which simplifies wiring in single-phase sub-circuits where both poles need isolation.
