Its interrupting capacity hits 187 kA at 240 V, 121 kA at 415 V and 440 V, 79 kA at 500 V, and 4.25 kA at 690 V — so the same breaker handles high-fault service entrances (187 kA at 240 V) and downstream distribution (121 kA at 415 V) without needing a current-limiting upstream device. The 4.25 kA at 690 V figure is the ceiling for 690 V line-to-line circuits; if your panel feeds a 690 V motor drive, verify the available fault current stays under that.
Thermal derating and ambient limits
At 55 °C it derates to 96.25 A, at 60 °C to 92.5 A, at 65 °C to 88.75 A, and at 70 °C to 85 A.
Trip unit and auxiliary configuration
The overcurrent release is an ETU560 electronic trip unit — that means adjustable long-time, short-time, instantaneous, and ground-fault protection curves, plus communication capability. Ground fault monitoring uses summation current formation on the L-conductor.
