Breaking capacity is 50 kA Icu at 380/415 V AC 50/60 Hz per IEC 60947-2, and the same rating at 440 V AC. That puts it in the N breaking-capacity class — enough headroom for most distribution boards downstream of a transformer, and it coordinates well with smaller downstream breakers. At 480 V AC it holds 50 kA Icu per UL 60947-4-1, so it works in North American 480Y/277 V panels too.
Backplate-mounted, 140 mm wide × 161 mm high × 86 mm deep. IP40 enclosure protection, IK07 impact rating. Mounts horizontally or vertically flat on the backplate — no derating for orientation in still air.
