It carries a continuous current rating of 160 A at 40 °C, holds the same rating through 50 °C, then derates to 156 A at 55 °C and 142 A at 70 °C — a thermal curve worth checking if your enclosure runs hot. The interrupting ratings are substantial: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, 30 kA at 500 V, and 17 kA at 690 V.
