Product details

D-curve 63 A MCB for high-inrush loads

The 5SY4163-8: The dual rating means it qualifies for both residential-distribution (60898) and industrial-installation (60947) applications.

Thermal derating and ambient limits

Rated current is 63 A at 35 °C ambient. For a panel that runs warm — say 50 °C inside the enclosure — the breaker handles about 55 A continuously without tripping on thermal overload.

Width is 18 mm — one modular unit (1 MW) on a DIN rail.
