Breaking capacity runs from 187 kA at 240 V down to 9 kA at 690 V, with 121 kA at 415 V and 440 V, and 75.6 kA at 500 V. That gives you selectivity headroom for most low-voltage distribution and motor branch circuits.
The depth of 110 mm (4.33 in) means it clears most standard enclosure depths without forcing a deeper can.
121 kA at 415 V, and the same at 440 V. At 240 V it reaches 187 kA.
