It carries a 70 kA breaking capacity per IEC 60947-2 at 400 V AC, with 15 kA at DC under the same standard, and 5 kA per UL 1077 / CSA C22.2 No. 235. Rated current is temperature-sensitive. At 45 °C ambient the 0.5 A rating holds; at 50 °C it derates to 0.49 A, at 55 °C to 0.47 A. The operating range spans -40 °C to 75 °C, with humidity limits stepping down as temperature rises — 95% RH up to 55 °C, 55% RH to 70 °C, 35% RH to 75 °C. If the panel runs hot, factor the derating into your load calculation. Mounts in any position, uses the quick-assembly system for ganging multiple breakers. Touch protection is built in. ## Construction and compliance Halogen-free and silicon-free construction. Sealable for tamper-proofing in metering or critical circuits. The neutral conductor is switched (3P+N configuration). Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz. This is a standard SENTRON catalog item, widely specified in industrial and mechanical engineering panels.","metaTitle":"Siemens 5SY8605-7 SENTRON MCB, 4P C 0.5A, 70kA","metaDescription":"Siemens 5SY8605-7 SENTRON miniature circuit breaker, 4-pole, C-curve 0.5A, 70kA IEC breaking capacity.
