The 3-pole frame breaks fault currents up to 187 kA at 240 V, 121 kA at 415 V, and still clears 9 kA at 690 V.
Ratings that matter for the panel
That means you can dial in selectivity with downstream breakers instead of oversizing the whole string. Thermal derating is published across the operating range: 630 A at 40 °C drops to 520 A at 70 °C (–). Maximum power loss is 162 W, which adds to the enclosure heat budget; factor it into your ventilation calc. No trip indicator and no communication function, so this is a straight power breaker, not a smart metering device.
