What this MCCB does and where it fits
It carries an 80 A continuous rating at 40 °C and holds that same 80 A all the way up to 50 °C; above that it derates gently to 74 A at 70 °C, so in a hot enclosure you still get most of the rated current. Breaking capacity is 75.6 kA at 240 V AC and 52.5 kA at 415 V AC, which covers high-fault utility feeds. It's IP40 on the front — fine for a dry indoor panel, not for washdown.
The 3VA1180-3ED22-0AA0 measures 130 mm high, 50.8 mm wide, and 70 mm deep — that's roughly 5.1 by 2 by 2.8 inches. Two-pole width at 50.8 mm is standard for a 2-pole MCCB in this class, so it drops into a DIN-rail or panel-mount assembly without re-drilling the gland plate. Insulation voltage is rated 500 V, so it's fine on 480 V systems with margin.
