Siemens 5SY4116-5 SENTRON MCB — Characteristic A, 1-Pole
The Siemens 5SY4116-5 is a 1-pole SENTRON miniature circuit breaker with tripping characteristic A, rated 10 kA breaking capacity per EN 60898-1 and 20 kA per IEC 60947-2 at 400 V AC. The characteristic A curve means it trips instantaneously on short-circuit currents between 2 and 3 times rated current — designed to protect semiconductor circuits and sensitive loads where even a brief overcurrent can damage components. Rated operating voltage is 400 V AC (440 V AC for single- or multi-phase operation) and 60 V DC (max 72 V DC). This is a current-production part (lifecycle stage: current).
Standards & Compliance — IEC, UL, CSA
The 5SY4116-5 is certified to IEC / EN 60898-1 and IEC / EN 60947-2, plus UL 1077. At UL/CSA ratings the breaking capacity is 5 kA.
Panel Fit & Mounting
Mounts in any position — no derating needed for horizontal or inverted orientation. Fastens via the quick-assembly system (snap-on). The combined terminal at top and bottom accepts supply from either end. Sealable for tamper-proofing after commissioning. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.
Environmental Range
Humidity influence: max 95% at 55 °C, derating to max 55% at 70 °C and max 35% at 75 °C.
