The Siemens SENTRON 5SV9316-7PK16 is a 2-pole RCBO — an RCD-operated circuit breaker combining overcurrent and residual current protection in a single 18 mm wide module. It is rated 16 A at 30 °C with a 30 mA residual current trip threshold, Type A (pulsating DC and AC sensitive). The tripping characteristic is Class C, instantaneous design, meaning it trips on short-circuit without intentional delay. Breaking capacity is 6 kA per both EN 60898 and IEC 60947-2, which covers the majority of residential and light commercial distribution board fault levels.
Above that, the continuous current must be derated: 15.2 A at 40 °C, 14.72 A at 45 °C, 14.24 A at 50 °C, and 13.76 A at 55 °C. The maximum operating ambient is 75 °C, minimum -40 °C.
