What this 5SP9206-7KC47 does in the panel
It breaks 50 kA at 400 V AC per IEC 60947-2 — that is the industrial-grade interrupting rating, not the residential 10 kA you see on EN 60898 devices. At 6 A it is sized for a 1.5–2.5 mm² copper circuit feeding a control panel or a small machine branch.
Mounting and wiring — DIN rail fit
It occupies 3 width units (roughly 54 mm on the rail). Installation depth is 92 mm, so it clears most shallow enclosures.
Rated for -40 °C to +75 °C ambient — wide enough for unheated warehouses or roof-top enclosures in most climates. Humidity tolerance up to 95% RH at +55 °C, periodic. Shock resistance 150 m/s² at 11 ms half-sine, vibration 50 m/s² at 25–150 Hz and 60 m/s² at 35 Hz (4 s). Mechanical life 20 000 switching cycles — typical for an MCB in a panel that sees occasional manual isolation, not daily load switching.
