It combines ground-fault and overcurrent protection in a single 36 mm-wide (2 MW) module, rated 16 A with a C tripping characteristic and 4.5 kA breaking capacity per EN 60898.
The 16 A rating at 30 °C is the base; it derates to 12.32 A at 70 °C, so if this RCBO sits in a crowded, hot enclosure, you need to account for that thermal curve — the 16 A label doesn't hold at elevated ambient. The 77 mm depth plus 70 mm installation depth means it fits standard 18 mm-module distribution boards — no special enclosure needed.
