That means it's still a standard catalog item, specifiable into new designs without a last-time-buy clock. RoHS-compliant since June 2013, with REACH Article 33 disclosure for lead above 0.1% (CAS 7439-92-1) in the current candidate list. ## What the 10 kA rating means on the van If your service entrance has a higher available fault current (say 18 kA or 25 kA upstream), you'd need a current-limiting upstream breaker or a higher-rated MCB. For branch circuits downstream of a 10 kA-rated main, this fits without derating.","metaTitle":"Siemens 5SL4163-8CC MCB 63A D-curve 1-pole 10kA","metaDescription":"Siemens 5SL4163-8CC miniature circuit breaker, 63 A, D-curve, 1-pole, 10 kA at 230/400 V.
