Part identity and key ratings
The Siemens 5SY4116-7CV is a SENTRON 5SY4-series miniature circuit breaker (MCB) rated at 16 A with a C tripping characteristic, single-pole construction, and a 15 kA breaking capacity tested to IEC / EN 60947-2. The C-curve means it trips between 5 and 10 times rated current — suited for mixed resistive and moderate inductive loads such as general-purpose branch circuits in industrial control panels.
Breaking capacity and selectivity
At 15 kA per IEC 60947-2, this breaker clears fault currents up to that level without upstream device intervention — a key number for panel SCCR coordination. The 1-pole design switches only the phase; neutral is not switched. Rated for 230 V AC single-phase operation and 250 V AC maximum under single-phase conditions.
Panel integration and environmental fit
Occupies 1 modular width unit (18 mm) on DIN rail, with a depth of 76 mm and installation depth of 70 mm. Mountable in any position. IP20 with connected conductors — suitable for enclosed panel installation, not for washdown or outdoor exposure. Operating temperature range from -40 °C to 75 °C, with humidity derating: max 95% RH up to 55 °C, tapering to 35% RH at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Power loss is 1.8 W per pole in hot operating state.
Compliance and approvals
Designed to IEC / EN 60947-2 for industrial applications. Pollution degree 3, overvoltage category III. Halogen-free and silicon-free construction. Sealable for tamper-proof installation. Supplementary devices (auxiliary contacts, shunt trips, undervoltage releases) can be installed as product extensions.
