That 50 A holds flat from 40 °C up to 50 °C, then derates gradually to 45 A at 70 °C — useful if it lands in a warm panel next to drives or transformers. Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. That 75.6 kA at 240 V covers high-fault industrial panels; the 52.5 kA at 415 V handles most European distribution boards.
