What the ratings mean for your panel
The Siemens 5SL6413-7 is a SENTRON 4-pole miniature circuit breaker with a C-curve tripping characteristic, rated 13 A at 30 °C and 6 kA breaking capacity per both EN 60898 and IEC 60947-2. The C-curve means it trips between 5 and 10 times rated current — standard for motor and transformer inrush where you need a bit of headroom over a B-curve but still protect branch wiring. The 6 kA rating tells you it can safely interrupt a fault up to that level without upstream coordination issues in a typical residential or light commercial distribution board. Rated voltage is 400 V AC, so it handles three-phase 4-wire supplies common in European infrastructure panels.
Mounting and integration
Mounts on standard DIN rail in any position. At 4 modular width units (72 mm wide), it takes four 18 mm slots in the distribution board. Depth is 76 mm (70 mm installation depth behind the panel face), so it fits flush in most consumer units and sub-distribution enclosures. IP20 with connected conductors — fine for dry indoor panels; not rated for washdown or outdoor exposure. Sealable terminals allow lockout-tagout compliance. Halogen-free and silicon-free construction meets low-smoke, zero-halogen material specs for public-building installations.
Derating and ambient conditions
Rated 13 A at 30 °C; derates to 12.37 A at 40 °C and 11.36 A at 55 °C. If your panel runs hot — say, a crowded enclosure near a furnace or in a rooftop cabinet — use the 40 °C figure for sizing. Ambient range is -40 to 75 °C operating, with periodic 95% humidity at 55 °C. Pollution degree 2 (normal, non-condensing) and overvoltage category III (fixed installation, distribution level).
