Its breaking capacity hits 242 kA at 240 V and 187 kA at 415 V, dropping to 4.5 kA at 690 V — so it handles high-fault industrial mains up to 480 V class comfortably, but the 690 V figure tells you this isn't a 690 V primary breaker. The 250 A rating holds flat from 40 °C to 50 °C, then derates to 200 A at 70 °C; if your panel runs hot, size the load accordingly. It carries a communication function for remote monitoring or trip indication, plus 2 auxiliary switches and a trip alarm switch (HQ design) built in.
That's a 3-pole MCCB footprint compatible with standard Siemens SENTRON mounting — bolts into a panel or mounts on a mounting plate. Width at 105 mm (4.13 in) sets the spacing for busbar or cable lugs.
The 250 A full-scale rating with a 50 A initial value (adjustable thermal-magnetic or electronic trip range) covers motor feeders, distribution panels, or large branch circuits. The basic switch variant is 3VA2225-6JQ32-0AA0 if you need the base unit without auxiliary switches.
