It protects a 10 A outgoing circuit with a C-curve thermal-magnetic trip and integrates 300 mA earth-leakage detection, all in a single clip-on DIN-rail unit.
Breaking capacity is 6000 A Icn at 380...415 V AC, 50/60 Hz, per EN/IEC 61009-2-1. Earth-leakage protection is integrated at 300 mA sensitivity — a common setting for whole-circuit protection against cable insulation faults rather than personal shock protection (30 mA is the touch-safe threshold). This is a property-protection device, not a personnel-safety RCD. The unit occupies 10 x 9 mm pitches on the DIN rail (90 mm wide) and clips on without tools.
This is an outgoer device — it sits downstream of the main breaker or switch-fuse, protecting a final sub-circuit. That is enough for a 10 A circuit even with some voltage-drop margin on longer runs.
Electrical and mechanical durability are both rated at 20,000 cycles — that is typical for a molded-case RCBO and matches the expected service life in a distribution panel that sees occasional switching, not daily load-break operation.
