It carries a 10 kA breaking capacity per IEC/EN 60898-1 and 15 kA per IEC/EN 60947-2 at DC, with a UL/CSA rating of 5 kA per UL 1077 and CSA C22.2 No.235. This is a current-production part (lifecycle stage: active). ## Breaking capacity and dual-standard rating The 10 kA rating under IEC/EN 60898-1 covers the residential and light commercial fault-current range; the 15 kA DC rating under IEC/EN 60947-2 gives it headroom for industrial DC bus protection. The 5 kA UL 1077 / CSA C22.2 No.235 rating means it qualifies as a supplementary protector in North American panels — not a branch-circuit rated breaker under UL 489, so spec it accordingly if your BOM calls for UL 489 listing. The IP20 rating (with conductors connected) is standard for enclosed distribution boards — no washdown rating, so keep it behind a gland plate. The sealable design lets you lock the toggle position after commissioning to prevent unauthorized switching. Ambient temperature range spans -40 °C to 75 °C, with humidity derating above 55 °C (95% RH at 55 °C, down to 35% at 75 °C). Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz — fine for machine-mounted panels but not for direct engine-mount without additional damping.","metaTitle":"Siemens 5SY4480-6 SENTRON MCB, 4P B-Curve, 10kA IEC","metaDescription":"Siemens 5SY4480-6 SENTRON 4-pole miniature circuit breaker, B-curve, 10 kA per IEC 60898-1, 15 kA DC per IEC 60947-2.
