The RCBO integrates both overcurrent (MCB) and residual-current (RCD) protection in one device, saving a module width compared to separate units. Breaking capacity is 6 kA per EN 60898 and 7.5 kA per IEC 60947-2 — enough for most domestic and commercial sub-distribution boards where the prospective short-circuit current stays under those thresholds.
The 16 A rating applies at 30 °C ambient. At 40 °C it derates to 15.2 A, at 50 °C to 14.3 A, and at 70 °C to 12.5 A. If the distribution board runs warm — near a transformer or in a tight enclosure — use the 40 °C or 50 °C column for sizing. Depth is 72 mm (70 mm installation depth), width 36 mm (2 MW), height 85 mm. IP20 with connected conductors in an installed distribution board — standard for enclosed panels.
