Rated current derates with ambient temperature: 6 A at 35 °C, 5.51 A at 40 °C, 5.25 A at 45 °C, 4.97 A at 50 °C, and 4.69 A at 55 °C. If the panel runs hot — say 50 °C near a drive or transformer — the effective continuous current drops to 4.97 A, so size up one frame if the load is marginal. ## Deployment context Occupies 3 modular width units (54 mm wide, 76 mm deep, 90 mm tall) with a 70 mm installation depth behind the panel face. The part carries no UL or CSA listing in the evidence; compliance documentation (RoHS, REACH) is standard for Siemens SENTRON series. For a BOM line requiring a UL 489 listed MCB, verify the specific approval against your panel shop's requirements.","metaTitle":"Siemens 5SY4306-6CC SENTRON MCB, 3P B-6A, 10kA","metaDescription":"Siemens 5SY4306-6CC SENTRON miniature circuit breaker, 3-pole, B-curve, 6 A rated, 10 kA breaking capacity per EN 60898.
