The breaking capacity is rated per voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V.
Thermal derating and the TM210 release
Above that, the curve steps down: 19.2 A at 55 °C, 18.8 A at 60 °C, 18.4 A at 65 °C, and 18 A at 70 °C.
Auxiliary release and accessory integration
This variant includes a shunt trip (STL) as the auxiliary release design. The integrated auxiliary trip order code is 3VA9688-0BL33. There is no undervoltage release, no auxiliary contact version, no communication function, no phase failure detection, and no ground fault monitoring. The trip indicator is also absent. For applications requiring remote tripping via a control signal, the shunt trip is present; everything else must be added externally.
