At 30 °C it carries the full 3 A; derate to 2.84 A at 40 °C, 2.76 A at 45 °C, 2.67 A at 50 °C, and 2.59 A at 55 °C — the thermal curve governs real-world panel loading when the enclosure runs warm. Single-pole construction (1 MW width) snaps onto a DIN rail, occupies one modular unit (18 mm wide), and accepts conductors up to the listed cross-section. ## Integration notes Mounts in any position, installs 70 mm into the panel behind the DIN rail. Sealable terminals and halogen-free / silicon-free construction suit infrastructure and residential building installations where fire-load and outgassing limits apply. Rated for overvoltage category III, pollution degree 2, and vibration resistance 50 m/s² at 25 to 150 Hz per IEC 60068-2-6. Single-phase AC rated 250 V; multi-phase operation rated 440 V AC.","metaTitle":"Siemens SENTRON 5SL4103-7CC Miniature Circuit Breaker, 3 A C","metaDescription":"Siemens SENTRON 5SL4103-7CC miniature circuit breaker, 1-pole, 3 A C-curve, 10 kA breaking capacity.

The difference is the current rating: 3 A vs 20 A, so the branch circuit load must match the lower rating."},{"question":"What compliance documentation does Siemens provide for 5SL4103-7CC?","answer":"The part carries IEC 60898 rating (10 kA breaking capacity), overvoltage category III, pollution degree 2, and vibration resistance per IEC 60068-2-6.
