What the breaking capacity means for your panel
Its breaking capacity hits 121 kA at 240 V, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V — so it handles high-fault scenarios at common distribution voltages without cascading upstream.
Thermal derating — don't lose margin at elevated ambient
At 55 °C it derates to 15.36 A, at 60 °C to 15.04 A, at 65 °C to 14.72 A, and at 70 °C to 14.4 A.
Panel fit and mechanical endurance
The breaker is rated for 15 000 mechanical operations, which covers typical panel duty for years. Front protection is IP40, so it's splash-safe in a clean enclosure but not washdown-rated.
Integrated auxiliary and undervoltage release
The auxiliary contact order code for replacement is 3VA9608-0BB24.
