The 3P+N configuration includes a switched neutral, so it suits single-phase or three-phase circuits where neutral disconnection is required. Rated 20 A at 30 °C ambient; at 40 °C the continuous rating derates to 18.48 A, and at 55 °C to 15.92 A — factor this into panel thermal calculations if the breaker is in a warm enclosure. IP20 with connected conductors; touch protection is built in, so no additional finger-safe covers are needed for the terminals. Sealable and halogen-free, silicon-free construction — suitable for installations with strict material-compatibility requirements (e.g., clean rooms, medical facilities). Degree of pollution 2, overvoltage category III, energy limitation class 3.","metaTitle":"Siemens SENTRON 5SL4620-8 MCB, 3P+N, D-curve, 20 A, 400 V, 1","metaDescription":"Siemens SENTRON 5SL4620-8 miniature circuit breaker, 3P+N, D-curve, 20 A, 400 V AC, 10 kA breaking capacity per EN 60898.
