Product identity and key ratings
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. The insulation voltage (Ui) is rated 264 V, overvoltage category III, pollution degree 2 — standard for fixed-installation final circuits.
Thermal derating and ambient limits
The 16 A rating holds at 30 °C ambient. 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. Mounting position is any, which simplifies panel layout.
DIN-rail footprint and installation
The 5SV9316-7PK16 occupies 1 modular width unit (18 mm) on a standard DIN rail. Depth is 77 mm, height 90 mm, installation depth 70 mm. The supply cord connects from below. Touch protection is provided per the product feature. IP20 rating applies when installed in a distribution board with connected conductors.
