It is configured for line protection — the standard role of guarding a feeder or distribution bus against overload and short-circuit faults.
Breaking capacity — what the voltages tell you
The interrupting rating is voltage-dependent, as you would expect for an MCCB. At 240 V it clears 187 kA; at 415 V and 440 V that drops to 121 kA, then 79 kA at 500 V, and 4.25 kA at 690 V.
Above that, derating applies: 96.25 A at 55 °C, 92.5 A at 60 °C, 88.75 A at 65 °C, and 85 A at 70 °C.
Built-in auxiliaries and trip options
The integrated auxiliary trip module is order code 3VA9688-0BL30. The base switch itself is 3VA2110-5JQ32-0AA0 — the -0HH0 suffix adds the communication function and the specific auxiliary/trip package.
The 105 mm width is standard for a 3-pole 100 A frame in the 3VA2 series — it occupies the same footprint as other 3VA2 breakers in this current class, so swapping between variants within the series doesn't require re-drilling the gland plate.
