Breaking capacity drops with system voltage: 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. The 690 V figure is low enough that coordination studies should verify selectivity at that voltage level.
Above 50 °C the current must be derated: 60.6375 A at 55 °C, 58.275 A at 60 °C, 55.9125 A at 65 °C, and 53.55 A at 70 °C. The 4 W maximum power loss is modest for a 63 A frame — panel ventilation is still advisable in sealed enclosures.
Auxiliary and trip options
The integrated auxiliary trip is order code 3VA9688-0BL30. No undervoltage release, no ground fault monitoring, no communication function, no phase failure detection — this is a straightforward line-protection breaker without add-on modules.
