Rated 1.6 A at 35 °C, derated to 1.52 A at 40 °C, 1.48 A at 45 °C, 1.44 A at 50 °C, and 1.4 A at 55 °C — the thermal derating curve is published, so a panel ambient above 35 °C reduces the continuous current the breaker can carry without nuisance tripping. The 6 kA rating under EN 60898 covers residential and light commercial service; the 30 kA rating under IEC 60947-2 / UL1077 covers industrial installations where available fault current is higher. Mounting position any, fastening via quick assembly system — clips onto the rail without tools.","metaTitle":"Siemens 5SY6515-7 SENTRON MCB, 1.6 A, C-Curve, 2-Pole, 6 kA","metaDescription":"Siemens 5SY6515-7 SENTRON miniature circuit breaker, 1.6 A rated, C tripping characteristic, 2-pole 1P+N, 6 kA (EN 60898) / 30 kA (IEC 60947-2).
