Its interrupting capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that tell you this breaker handles high-fault utility feeds or transformer secondaries without cascading upstream. At 690 V it still clears 11.9 kA, which matters for 690 V drives or mining gear. That simplifies spares planning: one order code, one amp rating, no risk of a swapped trip unit mis-match.
Above that it derates: 60.48 A at 55 °C, 59.22 A at 60 °C, 57.96 A at 65 °C, and 56.7 A at 70 °C. IP40 on the front face.
