Panel fit and thermal derating
The 5SY4616-7CV is a 4-pole miniature circuit breaker with C-curve tripping characteristic, rated 16 A at 35 °C and 15 kA breaking capacity per IEC 60947-2. The rated current derates with ambient temperature: 15.12 A at 40 °C, 14.66 A at 45 °C, 14.2 A at 50 °C, and 13.68 A at 55 °C. For a panel builder, that means a 16 A breaker in a 50 °C enclosure is effectively a 14 A device — plan your load margin accordingly.
Integration notes
Mounts in any position via the quick assembly system. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz. Suitable for mechanical engineering and industry per the manufacturer's classification.
