The interrupting capacity varies by voltage: 187 kA at 240 V, 121 kA at 415 V, 36 kA at 440 V, and 17 kA at 690 V — so at typical 400 V class distribution voltages it clears faults well above the available short-circuit current in most industrial panels.
Above that the current must be derated: 243.3 A at 55 °C, 236.5 A at 60 °C, 229 A at 65 °C, and 223 A at 70 °C.
The 4-pole width is the critical dimension for panel layout — it occupies roughly the same footprint as other SENTRON 4-pole frames in the 250 A class.
