Interrupting capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — so it clears high-fault events across common industrial voltages without upstream coordination headaches.
Ratings that matter for fit
At 55 °C it drops to 30.72 A, at 60 °C to 30.08 A, at 65 °C to 29.44 A, and at 70 °C to 28.8 A.
Auxiliaries and releases
The integrated auxiliary trip order code is 3VA9688-0BL30. No undervoltage release, no communication module, no ground fault monitoring. If you need those, you're looking at a different 3VA variant.
Physical integration
Three-pole, panel-mount or DIN-rail compatible per the SENTRON 3VA family standard. Latching endurance is rated at 15 000 operations — adequate for a distribution feeder that sees infrequent switching but needs reliability over decades. The trip indicator and voltage trigger are built in, so troubleshooting a tripped breaker is straightforward: visual confirmation plus a signal from the auxiliary alarm contact.
