The 3VA2325-6JQ32-0AA0: The 242 kA at 240 V and 187 kA at 415 V are the interrupting ratings for this frame — not the continuous load. For a site electrical engineer building a coordinated distribution board, those numbers give selectivity headroom downstream: you can size feeder breakers with lower interrupting ratings and still clear a fault before this main trips.
Thermal performance and derating
That's unusual for a molded case breaker; most frames start dropping current above 40 °C. Power loss is 37.5 W maximum, which matters for enclosure heat rise calculations.
