The 63 A rating holds flat from 40 °C to 50 °C; above that, it derates to 60.48 A at 55 °C and 56.7 A at 70 °C — factor that into panel ambient if you're pushing the thermal budget.
This MCCB delivers 187 kA at 240 V, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 17 kA at 690 V.
Latching endurance is 20,000 operations; the maximum power loss is 75 W, so account for that in thermal calculations if you're grouping several breakers.

121 kA at 415 V. The same rating applies at 440 V. At 240 V it is 187 kA, at 500 V it is 75.6 kA, and at 690 V it is 17 kA.
Yes, it includes a shunt trip (STL) auxiliary release and two HQ auxiliary switches. No undervoltage release or communication function is fitted.
59.22 A at 60 °C. The 63 A rating holds from 40 °C to 50 °C, then derates to 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C.
