Rated at 20 A with a C-curve trip characteristic and 10 kA breaking capacity (Icn at 230…240 V AC, 50 Hz, per EN/IEC 61009-2-1), it integrates 300 mA earth-leakage protection into the same thermal-magnetic trip unit.
Clip-on mounting to DIN rail (EN/IEC 61009-2-1 standard rail). The 36 mm width occupies 4 modules at 9 mm pitch. Neutral is on the left, phase on the right — fixed orientation, so plan the busbar and feed order accordingly. Terminals accept 1…16 mm² rigid or 1…10 mm² flexible (with or without ferrule); tightening torque is 2 N·m. Strip length 15 mm. The toggle provides local signalling: ON, OFF, and fault-trip indication.
Durability and electrical endurance
Rated for 20,000 mechanical cycles and 20,000 electrical cycles — the same figure for both, which is typical for a residential-grade RCBO. The limitation class is 3 per EN/IEC 61009-2-1, meaning it limits the let-through energy (I²t) to a defined level for better downstream coordination.
