Breaking capacity runs from 121 kA at 240 V AC down to 11.9 kA at 690 V AC, so the same breaker can serve a 480 V panel with plenty of fault-current headroom or a 690 V drive input with a lower SCCR requirement.
Above that the TM release begins to derate: 62 A at 55 °C, 61 A at 60 °C, 60 A at 65 °C, and 58 A at 70 °C. Maximum power loss is 17.3 W, which matters for heat buildup in a sealed cabinet.
Breaking capacity by voltage — selectivity planning
The interrupting ratings are: 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. For a 400 V distribution board with a 50 kA prospective fault current, this breaker clears with margin.
