It's a 1P+N design, meaning it switches the line conductor and monitors the neutral, with overcurrent protection on the line pole only. The C tripping characteristic (magnetic release at 5–10× In) handles motor-starting inrush and moderate inductive loads without nuisance trips. Rated 6 A at 30 °C ambient, the part thermally derates to 5.64 A at 40 °C, 5.46 A at 45 °C, 5.22 A at 50 °C, and 4.86 A at 55 °C — a curve that matters when the breaker is packed into a warm enclosure alongside other heat sources. ## Panel integration and mechanical fit ## Environmental and electrical endurance Halogen-free and silicon-free construction. The insulation voltage (Ui) is 264 V, surge voltage resistance is 4 000 V, and surge current resistance at 8/20 μS is 1 kA.","metaTitle":"Siemens 5SU9356-1KK06 SENTRON RCBO, 6A C-curve, 6kA/10kA","metaDescription":"Siemens 5SU9356-1KK06 SENTRON RCD-operated circuit breaker, 1P+N, 6A rated, C characteristic, 6kA per EN 60898 / 10kA per IEC 60947-2.
