The interrupting ratings climb to 52.5 kA at 240 V AC and still deliver 32 kA at 415 V, so it holds fault clearance across common industrial supply voltages without cascading upstream.
The 52.5 kA at 240 V is the headline figure, but the real-world fit depends on your system voltage: 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The thermal derating curve is flat from 40 °C to 50 °C (full 80 A), then drops to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. For a panel running at 60 °C ambient, you lose 3 A — plan the load margin accordingly.
The 3VA1080-2ED36-0AD0 measures 130 mm high, 76.2 mm wide, and 70 mm deep — a standard MCCB footprint for 3-pole frames in this class.
