It handles 160 A continuously up to 50 °C, then derates to 150 A at 70 °C — so in a warm panel you lose about 6 % of the headline current, which matters when sizing for a full-load motor feeder. Breaking capacity climbs with system voltage: 75.6 kA at 240 V AC, 52.5 kA at 415 V, 32 kA at 440 V, and holds 11.9 kA all the way to 690 V. That 11.9 kA at 690 V is the number to check if you are feeding a 690 V drive line — many MCCBs collapse harder above 500 V. The front face carries IP40 — fine for a clean panel, but not washdown.
Snaps onto standard DIN rail. Maximum power loss is 38 W — account for that in the enclosure thermal budget if you are packing several breakers in a small cabinet.
