It combines a 20 A thermal-magnetic MCB (C-curve) with integrated 10 mA earth-leakage protection, all in a 3P + Ns pole configuration. The 6 kA Icn breaking capacity at 400/415 V covers the fault-current duty of most commercial and light-industrial final subcircuits. Clip-on mounting to DIN rail, 54 mm wide (6 x 9 mm pitches), with screw-clamp terminals accepting 1…25 mm² rigid cable.
The 20 A rated current at 30 °C sets the continuous load limit for the protected circuit — sized for lighting, socket outlets, or small equipment banks. The 10 mA earth-leakage sensitivity is below the standard 30 mA for socket-outlet circuits; this RCBO would be specified where personnel protection or equipment sensitivity demands a lower leakage threshold — think medical locations, wet areas, or circuits feeding sensitive electronics. The 6 kA Icn at 400/415 V is the short-circuit breaking capacity; in a TN earthing system with a prospective fault current below 6 kA, this unit coordinates without upstream reinforcement.
Panel integration
Clip-on mounting to DIN rail with a 45 mm grid distance. The 54 mm width occupies six 9 mm pitches on the rail — plan panel fill accordingly. Screw-clamp terminals on top accept 1…25 mm² rigid cable; wire strip length 11 mm for bottom connection. Tightening torque 2.5 N.m. Neutral position is left, important when laying out busbar links or pre-wired distribution blocks. IP20 means no washdown tolerance; keep this inside a closed panel or enclosure.
