Breaking capacity — the real number
This breaker's interrupting rating is what you spec around. At 240 V it clears 187 kA; at 415 V it's 121 kA; at 440 V it drops to 75.6 kA; at 690 V it's 17 kA. The 690 V figure is low enough that you'd check the available fault current if the breaker lands in a 690 V wind or industrial application.
At 55 °C it derates to 38.4 A; at 60 °C to 37.6 A; at 65 °C to 36.8 A; at 70 °C to 36 A. Plan the branch load accordingly.
Integrated shunt trip and auxiliary options
That means remote tripping via a control signal is built in without external add-on hardware. No undervoltage release, no auxiliary contact, no ground-fault monitoring, no communication function. If you need those, this is not the variant; you'd look at a 3VA1 with the appropriate suffix. Mechanical endurance is rated at 15,000 operations.
