Its interrupting capacity reaches 330 kA at 240 V and 242 kA at 415 V, dropping to 3 kA at 690 V — so it handles high-fault scenarios on the low-voltage side but is not intended for 690 V primary protection.
Current rating and thermal performance
That flat curve is unusual; many breakers start tapering above 40 °C. Power loss is 7.7 W maximum, manageable in a sealed enclosure if airflow is adequate.
If you are stocking a critical spare for a legacy SENTRON panel, this one is still in the catalog and should be orderable without a last-time-buy scramble.
That 140 mm width on a 4-pole MCCB is compact for the class — check your existing DIN-rail or mounting-plate spacing before committing the BOM.
Communication and monitoring
Includes a communication function — the evidence does not specify the protocol, but the SENTRON 3VA platform typically supports PROFIBUS or PROFINET via a communication module. The ground-fault monitoring uses summation current on L+N, so it detects residual currents without a separate core-balance CT. No undervoltage release or trip indicator on this variant.
