Siemens SENTRON 5SL6316-7CC — 16 A C-Curve Miniature Circuit Breaker
The Siemens 5SL6316-7CC is a SENTRON miniature circuit breaker rated 16 A at 400 V AC with a C tripping characteristic, 3-pole design, and a 6 kA breaking capacity per EN 60898. Rated current derates with ambient temperature: 16 A at 30 °C, 15.28 A at 40 °C, 14.91 A at 45 °C, 14.53 A at 50 °C, and 14.14 A at 55 °C. If the panel runs warm — say 50 °C inside the enclosure — the effective continuous rating drops to 14.53 A, which matters when loading the circuit near its nameplate.
Snap-on DIN rail mount, any position. The IP20 rating applies with connected conductors. Vibration resistance tested to 50 m/s² over 25 to 150 Hz per IEC 60068-2-6 — adequate for most industrial panels but not heavy rotating machinery directly on the breaker.
Multi-phase operating voltage is 440 V AC maximum. The DC rating is 72 V maximum, so this is an AC-only breaker for typical branch panels.
