Its continuous current rating Iu is 63 A, and it holds that rating across the full ambient range from 40 °C to 70 °C — no derating needed up to the maximum operating temperature. Breaking capacity is the headline: 187 kA at 240 V AC, 121 kA at 415 V and 440 V, 75.6 kA at 500 V, and 3.7 kA at 690 V. The 690 V rating drops to 3.7 kA, so if your system runs at that voltage, verify the available fault current is below that threshold. The N-conductor protection is adjustable between OFF and 100%, which matters when you are protecting a 4-wire system and need to decide whether the neutral is switched or solid.
Power loss is rated at a maximum of 4 W, which is low enough that you do not need to account for significant heat buildup in a densely packed panel. Storage temperature range is -40 °C to 80 °C, and operating range is -25 °C to 70 °C — the storage limit is for handling and warehousing, not running.
