Above that, the thermal curve steps down: 375 A at 55 °C, 350 A at 60 °C, 325 A at 65 °C, and 300 A at 70 °C — so a panel running at 60 °C ambient loses 50 A of headroom. The interrupting capacity is the headline: 187 kA at 240 V, 121 kA at both 415 V and 440 V, 75.6 kA at 500 V, and 7.5 kA at 690 V. The adjustable trip range spans 600 A minimum to 4 000 A maximum, with an initial value of 80 A and full-scale of 400 A — the electronic trip unit is field-configurable for coordination studies.
No undervoltage release or other auxiliary release is fitted on this variant, so if undervoltage protection is needed, specify the release separately. Power loss is 96 W maximum at rated current — factor that into enclosure ventilation calculations.
