The interrupting ratings are what decide where this breaker fits in a fault-current study: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at 690 V.
Above that it starts to step down: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C.
What's built in and what's not
There's no auxiliary contact block, no ground-fault monitoring, no phase-failure detection, and no communication function. It's a straight line-protection breaker with a UVR and nothing else on the accessory rail. The integrated auxiliary trip is specified as order code 3VA9608-0BB25 — that's the factory-fitted UVR module. If you need to add auxiliary contacts or a shunt trip later, those are separate add-on accessories that mount to the breaker's side slots.
