63 A continuous, derated above 55 °C
Above that, the thermal curve steps down: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. That means in a warm panel — say 55 °C internal ambient — you lose 1 A of headroom; at 70 °C you lose 5 A.
Breaking capacity by system voltage
The interrupting rating drops as system voltage climbs — 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 480 V panel in North America, you're looking at the 440 V figure as the closest reference (32 kA). That's the number to check against your available fault current.
That's a standard MCCB cutout for a DIN-rail or screw-mount panel. IP40 on the front — fine for a dry indoor enclosure, not for washdown zones.
