The Siemens SENTRON 5SV9316-1PK06 is a 1P+N RCBO — a combined RCD and MCB in one 18 mm-wide module. It protects a single-phase final subcircuit against overload, short-circuit, and earth leakage in one unit, saving a DIN rail slot versus separate devices. The 30 mA residual-current element provides additional shock protection for personnel.
Integration notes
The 18 mm width (1 MW) fits standard modular enclosures. Supply connects from below; the design is instantaneous (no intentional time delay), so it trips within 40 ms on a residual fault. Touch protection is built into the terminals. Derate the thermal current above 30 °C: 5.64 A at 40 °C, 5.46 A at 45 °C, 5.22 A at 50 °C, 5.04 A at 55 °C. Ambient humidity up to 95% is within spec.
