The interrupting ratings are 52.5 kA at 240 V AC, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500/690 V — numbers that tell you it's sized for industrial panelboards and distribution boards where high fault current is expected.
The 25 A rating holds flat from 40 °C to 50 °C, then derates to 24 A at 55–60 °C and 23 A at 65–70 °C (–). At 415 V it still handles 32 kA, which covers most European industrial supplies. That gives you one NO/NC for status feedback and one for remote trip indication — enough for a typical feeder breaker but not a full complement. If you need more aux contacts, you'd add an external auxiliary switch block.
That 3-inch width is standard for 3-pole MCCBs in the SENTRON 3VA1 family, so it fits existing panel layouts without re-drilling.
