At 415 V and 440 V it still holds 121 kA, and at 500 V it interrupts 79 kA; only at 690 V does it drop to 4.25 kA, so it is primarily a low-voltage distribution breaker, not a 690 V motor-circuit device.
The 3VA2110-5HN32-0AB0 measures 105 mm wide by 181 mm tall by 86 mm deep — a standard SENTRON 3VA frame size that fits DIN-rail or screw-mount panel layouts. Plan your enclosure thermal budget accordingly if the breaker sits near transformers or drives.
Selectivity and coordination
With the ETU350 trip unit, this MCCB supports short-time delay settings for zone-selective interlocking or time-based coordination with downstream breakers.
