The Siemens 5SL4416-7CC is a SENTRON 5SL4 series miniature circuit breaker — 4-pole, C-curve, rated 16 A at 400 V AC, with a 10 kA breaking capacity per EN 60898. That 10 kA figure is the short-circuit current it can safely interrupt under fault conditions, which governs whether it coordinates with upstream protective devices in a distribution board. The C-curve (tripping between 5× and 10× rated current) suits it for mixed resistive and moderate inductive loads — lighting circuits, small motor feeders, and general-purpose branch protection in residential or light commercial infrastructure.
Dimensions and panel fit
At 72 mm wide (4 modular width units), it occupies four standard 18 mm DIN-rail slots. Depth is 76 mm overall, with an installation depth of 70 mm behind the panel face. Mounting position is unrestricted — any orientation is within spec. The IP20 rating applies only with connected conductors, so the busbar and wiring must be in place before the enclosure is considered finger-safe.
Environmental and compliance
Rated for ambient temperatures from -40 °C to +75 °C, with a humidity ceiling of 95% at 55 °C. The housing is halogen-free and silicon-free — relevant for panels in clean-room or corrosive-gas environments where outgassing matters. Pollution degree 2 (non-conductive deposits only) and overvoltage category III cover fixed-installation distribution boards. Vibration resistance is 50 m/s² over 25 to 150 Hz per IEC 60068-2-6.
