Its interrupting capacity hits 187 kA at 240 VAC, 121 kA at 415/440 V, 75.6 kA at 500 V, and 4.5 kA at 690 V — so the same breaker clears faults across a wide voltage range without swapping frames. The thermal curve is published from 40 °C through 70 °C: it holds the full 250 A up to 50 °C, then derates to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. Maximum power loss is 48 W, which feeds into the enclosure thermal budget.
The basic switch variant is 3VA2225-5HN42-0AA0; this listing adds two HP auxiliary switches.
