It carries a maximum breaking capacity of 242 kA at 240 V, stepping down to 187 kA at 415/440 V, 121 kA at 500 V, and 4.5 kA at 690 V — so it handles high fault currents on the low-voltage side while still clearing faults at higher voltages, though the 690 V rating is modest and worth checking against your system's available fault current. No ground-fault monitoring or communication function is integrated — this is a straightforward thermal-magnetic or electronic trip unit for main feeder or large branch protection.
Above that, it derates: 241 A at 55 °C, 232 A at 60 °C, 222 A at 65 °C, and 213 A at 70 °C. Plan your load margin accordingly, especially in a sealed enclosure.
The 3-pole footprint fits alongside other SENTRON breakers in a distribution board.
