Its breaking capacity scales with system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 4.5 kA at 690 V.
Above that it derates linearly: 238 A at 55 °C, 225 A at 60 °C, 213 A at 65 °C, and 200 A at 70 °C.
Built-in ground-fault monitoring and communication
This variant includes a ground-fault monitoring function using summation current formation on the L-conductor — it sums the phase currents and trips if the residual exceeds the threshold. That's a step up from a basic thermal-magnetic MCCB; it catches arcing ground faults that a standard trip unit might miss. Communication function is onboard, so it can report status and trip events to a PLC or BMS over the SENTRON bus system. No separate add-on module required for basic telemetry.
