It carries a continuous rated current of 100 A across the full ambient temperature range from 40 °C to 70 °C, meaning no derating is needed even in a warm enclosure — the same 100 A holds at 70 °C ambient.
This MCCB's interrupting capacity is 187 kA at 240 V AC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V.
Power loss is 10 W maximum, so thermal rise inside a sealed panel stays manageable without forced cooling.
At 415 V and 440 V the interrupting capacity is 121 kA; at 240 V it is 187 kA, at 500 V it is 75.6 kA, and at 690 V it is 3.7 kA.

No. The rated continuous current holds at 100 A from 40 °C through 70 °C ambient — no derating needed even in a warm enclosure.
