It protects a single-phase final subcircuit against both overload/short-circuit (thermal-magnetic trip, C-curve) and earth leakage (30 mA sensitivity). The 10 A rated current at 50 °C means it is sized for lighting or general-purpose socket circuits drawing up to 10 A continuous; the C-curve means magnetic trip occurs at 5 to 10 times In, so it tolerates moderate inrush from small motors or capacitive loads without nuisance tripping. The 30 mA earth-leakage threshold provides personal protection against indirect contact in TN earthing systems. Breaking capacity is 6000 A Icn at 240 V AC 50/60 Hz — sufficient for most residential and light commercial distribution boards where the prospective short-circuit current stays below 6 kA.
Clip-on DIN-rail mount — no screws needed. Terminals are screw-clamp: top accepts 1…25 mm² rigid or 1…16 mm² flexible; bottom accepts 1…16 mm² rigid or 1…10 mm² flexible. Wire stripping length is 14 mm for top connection, 13 mm for bottom. The device is padlockable with a Ø 4 mm padlock for lockout/tagout.
Certified to IEC 61009-1 and IEC 61009-2-2 — the international standard for RCBOs. The part carries limitation class 3, meaning it limits let-through energy under short-circuit conditions. Electrical durability is rated at 5000 cycles, mechanical durability at 20000 cycles. The device is suitable for isolation — it provides a visible break when toggled OFF.
