The frame is rated 480 A, meaning the physical bus and mechanism are sized for that maximum; the 40 A trip unit (ETU350 electronic overcurrent release) is what governs the actual load. Interrupting capacity is the headline: 330 kA at 240 V AC, 242 kA at 415/440 V, 187 kA at 500 V, and 3.7 kA at 690 V.
It mounts via the standard 3VA2 baseplate or direct panel-mount studs — no DIN rail adapter for this frame class. IP40 on the front face keeps finger-probes out but expects a dry enclosure — not a washdown location.
