The interrupting ratings are 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V, which covers most industrial panel fault-current requirements without needing a current-limiting upstream device.
The 80 A rating holds flat from 40 °C to 50 °C, then derates to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. The 15,000 mechanical endurance cycles are typical for a distribution breaker; it's not a switching-duty device for frequent motor starts.
The 3VA1180-3EF36-0KC0 measures 76.2 mm wide, 130 mm high, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or screw-mount panel layouts. The auxiliary trip accessory order code is 3VA9688-0BL33.
