The 5SY4216-7CV: The 15 kA breaking capacity at 400 V AC per IEC 60947-2 means this MCB can safely interrupt a fault current up to 15 kA without welding its contacts or cascading failure upstream — critical for selectivity studies in industrial distribution boards. The 16 A rating is at 35 °C ambient; the part derates to 14.83 A at 40 °C, 14.21 A at 45 °C, 13.6 A at 50 °C, and 12.86 A at 55 °C. The operating temperature range is -40 to 75 °C, with humidity limits of 95% up to 55 °C, 55% up to 70 °C, and 35% up to 75 °C. Rated for 440 V AC multi-phase operation, with a DC maximum of 72 V. The 2-pole design does not switch the neutral conductor.
Vibration resistance per IEC 60068-2-6: ±1 mm at 5–25 Hz, 50 m/s² at 25–150 Hz.
Designed to IEC / EN 60947-2. Halogen-free and silicon-free construction. Suitability for mechanical engineering and industry is stated by the manufacturer. The part is sealable for tamper-evident applications.
