Rated current derates with ambient temperature: 1.6 A at 45 °C, 1.57 A at 50 °C, 1.53 A at 55 °C. If your panel runs hot, the actual continuous load limit drops — plan for that in the BOM. The 15 kA DC rating per IEC 60947-2 covers DC distribution applications, and the 5 kA UL 1077 / CSA C22.2 No. 235 rating qualifies it for North American supplementary protection use.
