What this RCBO does and why the ratings matter
It's rated at 32 A (at 50 °C) with a 30 mA earth-leakage sensitivity, C-curve trip characteristic, and a 10 kA breaking capacity (Icn at 240 V AC, per IEC 61009-1). That 30 mA sensitivity is the standard for personal protection against electric shock in TN earthing systems — it catches leakage currents that could be dangerous through a person, while the C-curve handles moderate inrush from motor or lighting loads without nuisance tripping. The limitation class 3 rating (energy let-through) means it limits the fault energy passed downstream, which helps with selective coordination in a panel.
Clip-on mounting onto a 45 mm grid DIN rail — standard for Acti9 enclosures. Neutral is on the left, which matters when you're laying out busbars or pre-wired assemblies.
