Above that it derates: 38.4 A at 55 °C, 37.6 A at 60 °C, 36.8 A at 65 °C, and 36 A at 70 °C. The shunt trip release (design STL) is integrated as 3VA9688-0BL32. No auxiliary contacts, no undervoltage release, no ground-fault module on this variant. If your circuit requires those, this is not the order code.
Width 76.2 mm (roughly 3 module spaces), depth 70 mm, height 130 mm. No auxiliary contact block shipped with this code; if you need one, it must be ordered separately and installed in the field.
