The Siemens 5SJ6110-7 is a 1-pole SENTRON 5SJ6 miniature circuit breaker rated 10 A with a C tripping characteristic, breaking 6 kA per EN 60898 and IEC 60947-2 at 240 V AC.
Mounts in any position; supply cord can enter from either end. Rated IP20 with conductors connected, meaning it's intended for enclosed panels, not wet or dusty environments.
Electrical ratings and environment
Rated for AC/DC operation: 240 V AC single-phase or up to 60 V DC maximum. Insulation voltage is 440 V AC, and overvoltage category 3 means it's built for fixed-installation distribution panels where surges are expected. Energy limiting class 3 keeps let-through energy low, reducing stress on downstream equipment. Vibration resistance tested to 50 m/s² at 25–150 Hz and 60 m/s² at 10–150 Hz per IEC 60068-2-6 — good for industrial panels near rotating machinery. Mechanical life is 20 000 switching cycles typical.
Environmental and compliance details
Halogen-free and silicon-free construction — important for environments where outgassing can contaminate sensitive contacts or optics. Operating temperature range -40 to 75 °C, with periodic exposure to +55 °C and 95% humidity. Sealable cover and touch protection are standard. Degree of pollution 2 (non-conductive, occasional condensation).
