The Siemens 5SL4306-7CC is a SENTRON miniature circuit breaker (MCB) — 3-pole, C-curve tripping characteristic, rated 6 A at 400 V AC with a 10 kA breaking capacity per EN 60898. Rated current derates with ambient temperature: 5.76 A at 40 °C, 5.63 A at 45 °C, 5.5 A at 50 °C, 5.37 A at 55 °C. If your panel runs warm, size the load accordingly — the 6 A nameplate only holds at 30 °C. The 3-pole design handles three-phase circuits; the 400 V AC rated voltage and 440 V maximum multi-phase operation cover standard 230/400 V grids at 50/60 Hz.
Sealable, halogen-free, silicon-free construction for environments where outgassing matters. Vibration resistance rated at 50 m/s² over 25 to 150 Hz per IEC 60068-2-6, which covers typical industrial panel vibration. Power loss per pole is 0.7 W at rated current in hot operating state; total 2.1 W for the 3-pole unit — negligible for thermal budgeting inside a crowded enclosure.
