It also complies with UL1077, making it accepted in North American supplementary-protection applications. The dual rating means it can be specified for IEC panels (30 kA at the bus) while still fitting UL-listed machinery. ## Thermal derating and ambient limits Rated current is 10 A at 35 °C, but derates progressively: 9.39 A at 40 °C, 9.07 A at 45 °C, 8.74 A at 50 °C, 8.4 A at 55 °C, and 8.04 A at 60 °C. The ambient operating range spans -40 °C to 75 °C, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% at 75 °C.","metaTitle":"Siemens SENTRON 5SY7210-8 MCB, 2P, D-curve, 10 A, 15 kA","metaDescription":"Siemens SENTRON 5SY7210-8 miniature circuit breaker, 2-pole, D tripping characteristic, 10 A rated, 15 kA breaking capacity per EN 60898.
