It's a 3-pole unit rated for 630 A continuous current, which means it can feed a main bus or a large downstream panel without derating at 40 °C. Breaking capacity is the headline here: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 40 kA at 690 V. The overcurrent release is the ETU850 electronic trip unit, configurable for long-time, short-time, instantaneous, and ground-fault protection (though ground-fault monitoring is not fitted on this variant).
Above that, the unit derates linearly: 600 A at 45 °C, 570 A at 50 °C, 540 A at 55 °C, 510 A at 60 °C, 480 A at 65 °C, and 450 A at 70 °C. Footprint is 138 mm wide, 248 mm high, 110 mm deep. Maximum power loss is 162 W — noticeable heat in a sealed enclosure. Account for it in your thermal calculation if the panel is NEMA 12 or IP54.
