On a 400 V AC supply it delivers 10 kA breaking capacity per EN 60898, enough for most industrial sub-distribution boards; if you are wiring to UL 1077 standards the SCCR drops to 5 kA, so verify your available fault current before committing the BOM line. ## Panel fit and wiring constraints At 18 mm width (1 width unit) and 76 mm depth, it fits tightly into existing SENTRON sub-distribution boards without crowding adjacent breakers. The combined terminals top and bottom accept 0.75–35 mm² solid or stranded copper; tighten to 2.5–3.5 N·m with a Pozidriv screwdriver. Miniature circuit breakers with a D curve are specified for circuits with high magnetizing inrush — motor starters, solenoid banks, small transformers, and DC power supplies. The 5SY4113-8CC is rated for mechanical engineering and industrial environments per the manufacturer's own suitability listing.","metaTitle":"Siemens SENTRON 5SY4113-8CC MCB, 1P D 13A 10kA","metaDescription":"Siemens SENTRON 5SY4113-8CC miniature circuit breaker, 1-pole, D-curve, 13 A, 10 kA IEC breaking capacity, 400 V AC.

The difference is electrical: the 5SY4113-8CC is a 13 A D-curve; the 5SY7140-8CC is a 40 A C-curve.
