It carries a breaking capacity of 330 kA at 240 V AC, 242 kA at 415 V and 440 V, 187 kA at 500 V, and 3.7 kA at 690 V — numbers that tell you it can clear a serious fault without upstream coordination headaches.
That is unusual for a compact MCCB and simplifies panel thermal budgeting. The 4 W maximum power loss is low enough that natural convection in a standard IP54 enclosure handles it — no forced cooling needed.
Ground-fault and protection design
That means it sums the phase currents internally and trips on residual imbalance — no external GFCI module required. It is a line-protection design (not motor or generator protection), so the trip curve is shaped for cable and busbar thermal limits. If you need remote status or undervoltage lockout, this is not the variant — the 3VA2 family carries those options in other order codes. But for a straight line protection breaker with integrated ground-fault, this is the one.
No PCN or EOL notice on record.
