The Siemens 5SL4115-8CC is a 1-pole miniature circuit breaker with a D tripping characteristic, rated at 1.6 A and a breaking capacity of 10 kA at 230/400 V AC. It's built for protecting circuits that see high inrush currents — motor starters, transformers, discharge lamps — where a standard B or C curve would nuisance-trip on startup. The D curve allows a short magnetic trip delay, so it holds through the surge but still clears a hard fault fast.
Lifecycle status is active. No end-of-life notice or successor has been issued, so this order code remains the current production variant. The product class is B — return restricted — meaning the manufacturer controls distribution and returns, but for a standard procurement RFQ through independent channels, the part is sourced to order.
RoHS compliant since June 2013. REACH Article 33 disclosure notes lead (CAS 7439-92-1) above 0.1% w/w in the current candidate list. No UL or IEC certification entries appear in this record; the part carries the standard CE marking for the European low-voltage directive by virtue of its Siemens 5SL series pedigree.
