The front face is IP40 protected, which means it's sealed against tools and small wires but not against moisture ingress; keep it in a dry enclosure.
This MCCB delivers 75.6 kA interrupting capacity at 240 V AC, dropping to 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 (common in North American industrial), the 32 kA at 440 V is the closest published figure — the actual SCCR at 480 V will be between that and the 11.9 kA at 500 V, so verify coordination with the upstream transformer's fault current.
Above that, it derates linearly: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Mounting dimensions are 130 mm height, 76.2 mm width (3 inches — standard MCCB footprint), and 70 mm depth, so it fits a typical 3-inch-wide panel cutout without surprises.
