The Siemens 5SP9316-7KC47 is a SENTRON 5SP9 miniature circuit breaker — 3-pole, C-curve, rated 16 A at 400 V AC, with a 50 kA breaking capacity tested to IEC 60947-2.
Mounts on standard DIN rail or via screw fixing — any position works. At 4.5 width units, it occupies a compact footprint in the panel. Tunnel terminals top and bottom accept solid or stranded conductors from 0.75 mm² up to 50 mm² (AWG 14–2), with a tightening torque of 2.5–3.5 N·m (22–31 lbf·in).
Halogen-free and silicon-free construction. Shock resistance tested to 150 m/s² at 11 ms half-sine (IEC 60068-2-27); vibration resistance 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s) per IEC 60068-2-6. Mechanical service life typical 20,000 switching cycles.
