Breaking capacity is 4.5 kA per EN 60898 and 5 kA per IEC 60947-2 — the EN figure governs residential and light commercial distribution boards; the IEC figure applies when the breaker is used in industrial panel applications where the standard allows it. No official successor has been announced. The part remains a standard catalog item in the SENTRON 5SL series. The IP20 rating applies only with connected conductors — this is normal for a distribution-board MCB, not a standalone enclosure. Sealable design allows tamper-proofing in metered or secured installations. Designed for overvoltage category III, pollution degree 2. Rated for residential buildings and infrastructure. Halogen-free and silicon-free construction suits environments sensitive to outgassing (data centers, clean rooms). Mechanical service life is 20 000 operating cycles typical. DC rating is 72 V maximum.","metaTitle":"Siemens 5SL3620-7MB SENTRON MCB, 20A C-Curve 3P+N 400V","metaDescription":"Siemens 5SL3620-7MB SENTRON miniature circuit breaker, 20 A, C characteristic, 3P+N, 400 V AC, 4.5 kA (EN 60898).
