The Siemens SENTRON 5SJ6510-7KS is a 1P+N miniature circuit breaker from the 5SJ6 series, rated 10 A with a C-curve trip characteristic and a 6 kA breaking capacity per EN 60898 and IEC 60947-2. It switches the neutral conductor and accepts AC or DC supply voltage — 230 V AC nominal, 60 V DC maximum. Screwless outgoing terminals speed wiring in panel builds.
The 1P+N configuration switches both phase and neutral, with the neutral pole opening and closing with the phase — a requirement in many national wiring codes for final subcircuits. The IP20 rating applies only with connected conductors; the breaker itself is not sealed against dust ingress in the open state, so it belongs inside an enclosure, not exposed.
Mounting and integration notes
The 36 mm width means it occupies two 18 mm modular spaces — plan your rail fill accordingly.
