At 415 V and 440 V the rating holds at 121 kA; at 690 V it drops to 4.25 kA, so verify the available fault current at your service voltage. The 3-pole construction handles three-phase line protection, and the product version is explicitly line protection — not motor protection, so no overload class or phase-loss curve is built in.
At 55 °C it derates to 60.6 A, at 60 °C to 58.3 A, and at 70 °C to 53.6 A. Power loss is 4 W maximum, negligible for enclosure heat budgeting.
Trip unit and auxiliary configuration
It does not include ground-fault monitoring, undervoltage release, voltage trigger, phase-failure detection, or communication function. The auxiliary release design is without auxiliary release, meaning no shunt trip or UVR is factory-installed — those are separate add-on modules. The breaker has no trip indicator.
