Breaking capacity runs 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V, so it covers most low-voltage distribution panels and motor branch circuits without needing a current-limiting upstream device. An integrated undervoltage release (UVR) is factory-fitted — part number 3VA9608-0BB11 for the auxiliary trip assembly. That means if the control voltage drops, the breaker trips automatically, which is useful for safety interlocks or emergency-stop circuits that need to kill power when the control supply fails.
Ratings that matter for panel fit
The IP40 front protection means it's splash-proof from the front but not sealed — fine for indoor panels, not for washdown zones. Current rating holds at 80 A from 40 °C up to 50 °C, then derates to 76.8 A at 55 °C and 72 A at 70 °C. That thermal curve matters when you pack breakers tight in a panel — if ambient runs hot, you lose about 10% of the rating by 70 °C. Dimensions are 130 mm high, 76.2 mm wide, 70 mm deep — standard 3-pole MCCB footprint for this class. No auxiliary contacts are fitted, so if you need remote status feedback, you'll add those separately.
