The B-curve (3-5 In) trips fast on moderate overloads, so it pairs well with resistive or electronic loads that don't draw high inrush. Rated current derates with ambient temperature: 9.32 A at 40 °C, 8.96 A at 45 °C, 8.58 A at 50 °C, and 8.19 A at 55 °C. The device operates across -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C. This wide range covers unheated enclosures in cold climates and hot cabinet interiors near transformers or drives. IP20 with connected conductors; touch protection is built in. Sealable for tamper-proofing in metering or critical circuits. ## Construction and Compliance Halogen-free and silicon-free construction. Vibration resistance per IEC 60068-2-6: ±1 mm at 5-25 Hz, 50 m/s² at 25-150 Hz. Combined terminals on top and bottom simplify busbar and cable connections. No neutral conductor switching — this is a 2-pole device for DC or phase + phase protection. Designation per IEC 81346-2 and DIN EN 61346-2 is F (protective device). Marked as current-production. No official successor has been issued — this remains the active order code for new builds and spares.","metaTitle":"Siemens SENTRON 5SY5210-6CC MCB, 10A B-Curve, 2P, DC 440V","metaDescription":"Siemens SENTRON 5SY5210-6CC miniature circuit breaker, 10A rated at 35°C, B tripping characteristic, 2-pole, 10kA DC breaking capacity at 440V.
