At DC the 15 kA rating applies up to 60 V (72 V max). Neutral is switched (3P+N), which matters for panels where the neutral must be disconnected for isolation — common in industrial machine supply. Certified to IEC/EN 60898-1 and IEC/EN 60947-2, plus UL 1077 and CSA C22.2 No. 235 (5 kA at AC under those standards). The dual-standard coverage simplifies BOM compliance across regions — the same part number works for a panel built to IEC 61439 or a North American supplementary-protector application. Halogen-free and silicon-free construction, sealable, with energy limitation class 3.","metaTitle":"Siemens 5SY4625-6 SENTRON MCB, 4P B-curve, 10 kA","metaDescription":"Siemens 5SY4625-6 SENTRON miniature circuit breaker, 4-pole (3P+N), B-curve, 10 kA per EN 60898 / 20 kA per IEC 60947-2.
