The Siemens SENTRON 5SL4505-7 is a 1P+N miniature circuit breaker rated 0.5 A with a C tripping characteristic, breaking 10 kA at 230 V AC per EN 60898 and IEC 60947-2. The neutral pole switches with the line pole, so it clears both conductors on a fault — a standard requirement for single-phase final subcircuits in many European panel builds.
At 0.5 A it is sized for very low-current loads — control transformers, signal supplies, or pilot circuits — not general power outlets. Derate the rating when ambient exceeds 40 °C: at 55 °C the continuous current drops to 0.43 A.
Mounting position is any — can be installed horizontally or vertically without derating the breaking capacity.
