That matters for installations where the neutral must be positively isolated under fault or during maintenance. Rated 25 A at 45 °C ambient, 230 V AC, 50/60 Hz, with a D tripping characteristic designed for high inrush loads like motor starters, transformers, or capacitor banks. For DC circuits it is rated 15 kA per the same standard. If you are specifying for a UL 508A panel, note the UL 1077 / CSA C22.2 No. 235 rating is 5 kA; that is the listing for supplementary protection in North American industrial control panels, not branch-circuit protection.
Snaps onto a DIN rail (EN 60715) — the fastening method is a quick-assembly system, no tools needed for installation or removal. Halogen-free and silicon-free construction means the plastic housing does not emit corrosive halogen gases or silicone vapors under fire or thermal stress, important for clean environments like food processing or electronics assembly.
Compliance documentation available includes RoHS and REACH declarations; the brand provides a CE declaration of conformity per the Low Voltage Directive. The IEC 60947-2 rating is the primary standard for European and global installations.
Temperature derating and operating range
Rated current is 25 A at 45 °C ambient. At 50 °C it derates to 24.38 A; at 55 °C to 23.72 A. The maximum ambient is 75 °C, minimum -40 °C. The influence of surrounding temperature table gives the humidity limits: max 95% up to 55 °C, max 55% up to 70 °C, max 35% up to 75 °C. Vibration resistance per IEC 60068-2-6: ±1 mm at 5 to 25 Hz, 50 m/s² at 25 to 150 Hz. That covers most industrial machine vibration profiles.
