What this RCBO carries
Breaking capacity is 4.5 kA at 230 V AC. The Type A detection means it catches pulsating DC fault currents from half-wave rectified loads — common in modern switched-mode power supplies, LED drivers, and single-phase drives — not just pure sinusoidal AC leakage.
Snap-on DIN rail mount, 1 module width (18 mm). Occupies one slot in a consumer unit or distribution board. The 6 A C-curve protects lighting circuits, small fan coils, and control transformers up to that rating; the 30 mA RCD side covers personnel protection for the same final circuit. Single-pole switched, neutral solid — no neutral disconnect.
