The Siemens 5SJ6113-7KS is a SENTRON 5SJ6 series miniature circuit breaker (MCB) — 1-pole, C-curve, rated 13 A at 400 V AC, with a 6 kA breaking capacity per EN 60898 and IEC 60947-2. It snaps onto a standard DIN rail and occupies one modular width (18 mm). The C characteristic means it handles moderate inrush currents typical of lighting and small motor loads, tripping magnetically between 5 and 10 times rated current.
Integration & Mounting
Mounts in any position on a 35 mm DIN rail. Depth is 76 mm (70 mm installation depth plus terminals), width 18 mm — one modular unit. Screwless outgoing terminals accept solid or ferruled stranded conductors; strip length follows Siemens standard practice. IP20 with connected conductors, so it belongs inside a closed panel or distribution board.
