Breaking capacity hits 187 kA at 240 V AC, 121 kA at 415 V, and 75.6 kA at 440 V — enough to handle high-fault utility feeds or transformer secondaries without cascading upstream.
Above that it derates stepwise — 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, 144 A at 70 °C. That's a clean thermal curve for panel builders sizing in warm enclosures or near transformer banks.
What it doesn't carry
If your circuit needs any of those, you'll add them externally or step to a different 3VA variant. The integrated auxiliary trip is order code 3VA9688-0BL33 — that's the shunt-trip coil itself, not a separate accessory.
