The Siemens SENTRON 5SJ6110-7RC is a 1-pole miniature circuit breaker rated 10 A at 240 V AC with a C tripping characteristic and a 6 kA breaking capacity per EN 60898. It's part of the retail line, built for panelboard and distribution board use where you need moderate inrush handling — think lighting, general-purpose outlets, and small motor circuits that don't slam the breaker on startup.
What fits and what doesn't
Mount it any position you like; the breaker doesn't care.
Lifecycle and compliance — still a current part
That covers unheated utility rooms and hot panel interiors alike. The 6 kA breaking capacity at 240 V AC meets EN 60898 for residential and light commercial distribution; if you need higher fault current, step up to the 5SL series with 10 kA ratings.
