The 5SU1356-7KK16: The 16 A rating at 30 °C is the headline figure, but the derating curve matters in a warm panel: at 40 °C it's 15.2 A, at 50 °C it's 14.4 A, and at 60 °C it's 13.6 A. If your enclosure runs hot, size the load accordingly. The 6 kA (EN 60898) and 15 kA (IEC 60947-2) ratings give you headroom for high-fault installations; the 15 kA figure is the one to use for industrial coordination studies.
