The interrupting ratings span 75.6 kA at 240 V down to 10.5 kA at 690 V, so it handles high available fault current on the low-voltage side of a 480 V or 600 V panel. That gives you both a status mirror and a separate alarm contact for remote indication when the breaker trips on fault.
Above that it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C.

The 3VA1010-4ED36-0CC0 is a peer in the same SENTRON 3VA family, but it carries a different release (4ED36 vs TM240) and a lower interrupting rating. It will not drop into the same panel without verifying the trip curve and SCCR coordination — the TM240 thermal-magnetic curve and 40 A rating are specific to this order code.
Rated continuous current Iu is 40 A, with interrupting capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. The overcurrent release is a TM240 thermal-magnetic type. Insulation voltage Ui is 800 V.
