It also carries a DC breaking capacity of 15 kA at 60 V per IEC 60947-2 and a UL 1077 rating of 5 kA. The characteristic A curve means it trips almost instantaneously on overload — designed to protect sensitive semiconductor loads or long cable runs where fast clearing is required, not for general motor starting. ## Certifications and Environmental The 5SY4110-5 is certified to IEC/EN 60898-1, IEC/EN 60947-2, and UL 1077 / CSA C22.2 No.235. It is halogen-free and silicon-free, and rated for an ambient temperature range of -40 °C to 75 °C with defined humidity limits (95% at 55 °C, 55% at 70 °C, 35% at 75 °C). The overvoltage category is III and pollution degree is 3, making it suitable for industrial control panels and mechanical engineering environments.","metaTitle":"Siemens 5SY4110-5 SENTRON MCB, 1P, 10 kA, Characteristic A","metaDescription":"Siemens 5SY4110-5 SENTRON miniature circuit breaker, 1-pole, 10 kA per EN 60898-1, 20 kA per IEC 60947-2, characteristic A.
