The Siemens 5SP9313-7KC47 is a SENTRON 5SP9 miniature circuit breaker — 3-pole, C-curve, rated 13 A at 400 V AC.
At 4.5 width units (about 81 mm), it occupies three 18 mm pole positions plus one half-module — plan the DIN rail fill accordingly. 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). That cross-section range covers everything from control-circuit tails to main feeder tails in a sub-distribution board.
Protection class IP20 with connected conductors; overvoltage category III. Shock resistance tested to 150 m/s² at 11 ms half-sine per IEC 60068-2-27; vibration resistance to 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz per IEC 60068-2-6. Mechanical service life is 20,000 switching cycles typical.
