What this 5SP9 MCB brings to a panel
The Siemens 5SP9410-7KC47 is a 4-pole SENTRON miniature circuit breaker rated 10 A with a C-curve tripping characteristic, designed for 400 V AC supply at 50 Hz. Rated 10 A continuous, it handles typical branch circuits feeding contactor coils, relay panels, or small power supplies without nuisance tripping on startup. Accepts solid or stranded copper from 0.75 mm² to 50 mm² (AWG 14–2), tunnel terminals top and bottom. Tightening torque 2.5–3.5 N·m (22–31 lbf·in).
Where it lives in the panel
Shock resistance of 150 m/s² at 11 ms half-sine and vibration resistance per IEC 60068-2-6 (50 m/s² at 25–150 Hz, 60 m/s² at 35 Hz for 4 s) mean it holds up on a machine frame or in a transportable skid — not just a fixed wall panel.
