Mounting position is any, so you can lay it sideways in a shallow enclosure. IP20 with conductors connected — standard for enclosed panels, not for wet areas.
Rated for AC 400 V, overvoltage category III. Breaking capacity also rated at 5 kA per UL 1077 and CSA C22.2 No. 235, and 15 kA DC per IEC 60947-2. Halogen-free and silicon-free construction. Touch protection integrated. Ambient temperature range -25 to +55 °C; storage -40 to +75 °C. Humidity limits: 95% at 55 °C, derated at higher temps.
6 kA per EN 60898 for general distribution, 30 kA per IEC 60947-2 for industrial feeder duty, and 5 kA per UL 1077 / CSA C22.2 No. 235.
Solid or stranded conductors from 0.75 mm² up to 35 mm².
