At DC, it breaks 15 kA at 60 V (max 72 V). The 1-module width (18 mm) snaps onto DIN rail and fits any mounting position; combined terminals top and bottom simplify daisy-chaining. Deployment context: this breaker is suited for mechanical engineering and industrial control panels. Lifecycle status is current production. No phase-out or last-time-buy notice on record. The 5SY4140-5 is certified to IEC / EN 60898-1, IEC / EN 60947-2, and UL 1077. Vibration resistance per IEC 60068-2-6 covers ±1 mm at 5–25 Hz and 50 m/s² at 25–150 Hz. The breaker is sealable for tamper-proofing after commissioning. Humidity derating applies: max 95% up to 55 °C, then 55% up to 70 °C, then 35% at 75 °C. Mounting position is any; fastening is via quick-assembly system — standard DIN-rail clip. The 18 mm width matches a single modular unit, so it occupies one slot on the rail.","metaTitle":"Siemens 5SY4140-5 SENTRON MCB, 1P, Characteristic A, 10 kA","metaDescription":"Siemens 5SY4140-5 SENTRON miniature circuit breaker, 1-pole, tripping characteristic A, 10 kA per EN 60898, 15 kA per IEC 60947-2.
