That 630 A holds flat from 40 °C up to 50 °C, then derates to 583 A at 70 °C — so in a warm panel you still have headroom before you hit the trip curve. The interrupting capacity is where this part earns its keep: 220 kA at 240 V, 154 kA at 415/440 V, 121 kA at 500 V, and 17 kA at 690 V.
Overcurrent release and protection design
The design is line protection, meaning it's intended for feeder circuits, not motor branch protection (no motor-overload relay built in).
Dimensions: 248 mm high, 184 mm wide, 110 mm deep. That 184 mm width on a 4-pole breaker is standard for the frame size — it'll fit a 200 mm wide DIN-rail enclosure with a few mm to spare on each side. Front protection is IP40, so it's fine in a clean indoor panel; not rated for washdown.
