The 250 A rating holds flat from 40 °C to 50 °C; above that it derates to 223 A at 70 °C, so factor in enclosure ambient if the panel runs hot. This is a line-protection version — no undervoltage release, no ground-fault module, no communication. The adjustable response time tr max is 1 s, which gives some coordination flexibility on the time-current curve.
