Its interrupting capacity is 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 4.5 kA at 690 V — meaning it can safely clear fault currents up to those levels depending on the system voltage, which is critical for maintaining selectivity and protecting downstream equipment in high-fault installations. Rated continuous current holds at 250 A from 40 °C up to 50 °C ambient, then derates to 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C — useful when the breaker is installed in a warm enclosure or alongside other heat-generating devices.

Frequently asked questions
Will the 3VA2225-7HN32-0AB0 drop into a panel specified around the 3VA2225-5HN42-0BB0?
Both are 3-pole SENTRON 3VA2 breakers in the same frame size, so the physical footprint (105 mm wide, 181 mm high, 86 mm deep) is identical — no rewiring or panel modification needed for fit.
