What the ratings mean for fit
The 5SL4516-7CC is a SENTRON miniature circuit breaker with a 1P+N pole design and C-curve tripping characteristic, rated 16 A at 230 V AC. The C-curve (5–10× In) handles moderate inrush from lighting or small motor loads without nuisance trips, while the 10 kA breaking capacity per EN 60898 ensures it safely clears a short-circuit fault up to that level in a residential or light-commercial distribution board. The 2-module-width (36 mm) footprint fits standard DIN-rail enclosures; the 76 mm depth and 70 mm installation depth leave room for wiring in a typical consumer unit or sub-distribution panel.
Thermal derating and environmental limits
Rated 16 A at 30 °C ambient, the breaker derates to 14.78 A at 40 °C, 14.13 A at 45 °C, 13.45 A at 50 °C, and 12.74 A at 55 °C — the thermal curve governs continuous load, not the label. Operating range spans -40 °C to 75 °C, with IP20 protection (with connected conductors) suitable for clean, dry indoor panels. Pollution degree 2 and overvoltage category III align with fixed-installation switchgear. Vibration resistance tested to 50 m/s² at 25–150 Hz per IEC 60068-2-6, so it holds up in industrial environments near rotating equipment.
