It's a current-production part (lifecycle stage: active). For the panel builder: this is a DIN-rail mount unit, 2-pole wide, so it occupies two module spaces in the distribution board. Lifecycle is active. No end-of-life notice, no successor announced — this is the current catalog item. RoHS compliant since June 2013. REACH declares lead (CAS 7439-92-1) above the 0.1% threshold in the candidate list, so it's reportable under Article 33 but not banned. For a BOM freeze or compliance audit, the declaration pack is straightforward: no SVHC restrictions beyond the standard lead listing. On the van: if you're swapping a failed 63 A B-curve 2-pole in a lighting or general-power panel, this is the direct Siemens part number.","metaTitle":"Siemens 5SL4263-6CC Miniature Circuit Breaker, 2-pole, B, 63","metaDescription":"Siemens 5SL4263-6CC miniature circuit breaker, 2-pole, B-curve, 63 A, 400 V, 10 kA breaking capacity.
