The continuous current rating is 630 A at 40 °C, and it holds that same 630 A through 50 °C; at 55 °C it derates to 618 A, at 60 °C to 607 A, at 65 °C to 595 A, and at 70 °C to 583 A. The interrupting ratings are what decide whether this breaker clears a fault without upstream damage: 121 kA at 240 V, 75.6 kA at 415 V and 440 V, 52.5 kA at 500 V, and 11.9 kA at 690 V. The 3-pole form factor (138 mm wide, 248 mm tall, 110 mm deep) fits the standard SENTRON 3VA mounting footprint; it carries a built-in undervoltage release (UVR) and one auxiliary switch plus one trip alarm switch, which covers the basic status feedback to a PLC or annunciator.
