At 45 °C the continuous rating derates to 23.18 A, at 50 °C to 22.55 A, and at 60 °C to 21.2 A; if the panel ambient runs hot, size the upstream protection for the derated figure, not the 25 A label. Breaking capacity is 15 kA per EN 60898 and 25 kA per IEC 60947-2, with a DC rating of 15 kA per IEC 60947-2 and 5 kA under UL 1077 / CSA C22.2 No. 235. The 25 kA IEC figure gives headroom for high-fault installations — industrial panels with large transformers upstream.
IP20 with conductors connected — fine inside a closed panel, not for wet environments. Combined terminals top and bottom, sealable, halogen-free and silicon-free construction. Pollution degree 3, overvoltage category III. The sealable feature matters for installations that need tamper evidence — utility meters, rental equipment, or safety-critical circuits.
