It carries a continuous current rating of 80 A at 40 °C, derating to 74 A at 70 °C, which is the real-world figure for a warm enclosure — plan your load margin against that upper ambient, not the 40 °C number. Rated insulation voltage is 800 V, and the interrupting ratings span the common industrial voltages: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
