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 52.5 kA at 690 V.
Above that, derate linearly: 780 A at 55 °C, 761 A at 60 °C, 741 A at 65 °C, and 722 A at 70 °C. If your enclosure ambient runs hot — say a sealed NEMA 12 panel near a furnace line — factor the 55 °C or 60 °C column into your load study. Physical footprint: 210 mm wide, 320 mm tall, 120 mm deep. The depth of 120 mm (4.72 in) leaves clearance for rear-connected busbars or cable lugs in a typical 600 mm deep enclosure.
