RCBO for final-circuit protection — 4-pole, C-curve, 16 A
The breaking capacity is 6 kA per EN 60898 and also 6 kA per IEC 60947-2, so it clears faults up to that level in a 400 V AC, 50 Hz system.
Thermal derating and mounting flexibility
At 40 °C it derates to 15.2 A, at 50 °C to 14.3 A, and at 70 °C to 12.5 A — a straight thermal curve you must apply when the panel runs hot. The IP20 rating applies once the distribution board is installed with connected conductors — the front face is touch-safe, but the terminals need enclosure protection during handling.
