The B curve (3-5 In instantaneous trip) suits cable protection in residential and infrastructure runs where inrush from lighting or small transformers is modest. At 20 A it covers 2.5 mm² copper circuits in standard IEC installations. DC-rated maximum is 72 V, so it can also serve as a DC branch protector in control panels where the supply is rectified. ## How the ratings govern real-world use That means the same part can be specified for a house distribution board or a factory sub-panel without re-rating — a single BOM line covers both. Power loss is 2.5 W per pole in hot operating state at rated current. Not a frequent-switching device — this is set-and-forget overcurrent protection, not a contactor for motor cycling. For BOM freeze or compliance documentation, the part carries the standard Siemens declarations (CE, UKCA, EAC) for the 5SL family. RoHS and REACH compliance is standard for current SENTRON production.","metaTitle":"Siemens 5SL4620-6 SENTRON MCB, 3P+N, 20 A, B Curve, 10 kA","metaDescription":"Siemens 5SL4620-6 SENTRON miniature circuit breaker, 3P+N, 20 A, B characteristic, 10 kA breaking capacity per EN 60898/IEC 60947-2.

The 5SL4620-6 is 72 mm wide (4 MW) versus 54 mm (3 MW) for the 5SL4363-7. The 5SL4620-6 also has 4 poles (3P+N) versus 3 poles on the 5SL4363-7, so it needs an additional neutral conductor connection and more DIN space.
