The Siemens 5SV9313-7CN10 is a SENTRON RCBO — a residual-current-operated circuit breaker that packs overcurrent and earth-leakage protection into a single 18 mm-wide module. It's a 2-pole, 1P+N unit with a 10 A rated current and a 30 mA Type A residual-current trip. The C-curve characteristic means it handles moderate inrush (like small motors or lighting ballasts) without nuisance tripping. Rated breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — enough for most residential and light commercial distribution boards.
Thermal derating — the real-world current
At 40 °C it derates to 9.4 A, at 45 °C to 9.1 A, at 50 °C to 8.7 A, and at 55 °C to 8.4 A. If your panel runs warm — say, next to a drive or in a sunlit enclosure — size the load against the derated figure, not the label.
Snaps onto DIN rail, takes one modular width unit (18 mm). Depth is 77 mm, height 90 mm, installation depth 70 mm. Mounting position is any — no restriction on upright or sideways. Touch protection is built in.
