The interrupting capacity hits 187 kA at 240 V AC, 121 kA at 415/440 V, 79 kA at 500 V, and 4.25 kA at 690 V, so it handles high-fault scenarios without cascading upstream.
Thermal derating and trip unit
Above that, it derates linearly: 60.6 A at 55 °C, 58.3 A at 60 °C, 55.9 A at 65 °C, and 53.6 A at 70 °C. The electronic trip unit is an ETU320 — that's the fixed, non-communicating version, no ground-fault or phase-failure detection built in. If you need those, you're looking at a different trip deck.
Auxiliary and shunt trip configuration
The integrated auxiliary trip module is order code 3VA9688-0BL30. The basic switch (the breaker core without the aux package) is 3VA2163-5HL32-0AA0. That matters if you're swapping just the trip deck or need to match a panel's existing wiring scheme.
That depth (86 mm) is the key number for panel clearance — make sure the enclosure door clears the breaker handle and any protruding shunt-trip wiring.
