It also breaks 5 kA per UL 1077 and CSA C22.2 No.235 — so it handles both IEC and North American fault-current requirements in the same package. At 72 V DC maximum, it covers DC control circuits common in industrial panels. The C curve means it tolerates moderate inrush (typical of motor starters and small transformers) before tripping magnetically, making it a standard choice for general branch-circuit protection in machinery. Installation depth is 70 mm; the overall depth of 76 mm includes the actuator and terminal screws. Sealable, halogen-free, silicon-free — meets clean-room and food-grade panel requirements where outgassing must be controlled. Rated AC voltage: 400 V (single-phase and multi-phase operation up to 440 V). Frequency: 50/60 Hz. DC rated voltage: 72 V maximum. Ambient temperature range: -40 °C to 75 °C, with humidity derating: max 95% RH at 55 °C, falling to 35% at 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. Mechanical service life: 10 000 operating cycles typical. Energy limitation class 3 — limits let-through energy during a short-circuit to reduce stress on downstream components. Snap-on fastening to 35 mm DIN rail (EN 60715). No tools needed for mounting or removal. The combined terminal design accepts copper conductors up to the rated cross-section (verify local wiring regs). Suitable for mechanical engineering and industrial applications per the manufacturer's designation.","metaTitle":"Siemens 5SY4250-7CC SENTRON MCB, 2-Pole C-Curve, 10 kA","metaDescription":"Siemens 5SY4250-7CC SENTRON miniature circuit breaker, 2-pole, C characteristic, 10 kA per EN 60898. 400 V AC, 72 V DC.
