The 25 A rating at 35 °C derates to 23.8 A at 40 °C, 23.18 A at 45 °C, 22.55 A at 50 °C, 21.88 A at 55 °C, and 21.2 A at 60 °C; if your panel ambient runs above 35 °C, the continuous load must be reduced accordingly. The 10 kA SCCR per EN 60898 covers standard residential/commercial branch circuits; the 20 kA rating per IEC 60947-2 gives headroom for industrial distribution where fault currents are higher.
Deployment context — panel integration and environment
It can be installed in any mounting position. The design is explicitly for railway applications (product design: for railway applications), and the part is also rated for mechanical engineering/industry use.
