The 5SY4415-8: At 1.6 A, the magnetic trip threshold sits between 16 A and 32 A.
Rated current holds at 1.6 A up to 35 °C ambient, then derates linearly to 1.4 A at 60 °C. In a sealed, uncooled enclosure the effective continuous load should be budgeted against the 60 °C column unless the panel temperature is verified lower.
The IEC rating allows installation in industrial panels with higher prospective fault current than the EN rating alone covers.
