At 415 V and 440 V it still holds 187 kA, and at 500 V it's rated 121 kA; only at 690 V does it drop to 3 kA, so keep that in mind if you're on a 690 V system. That's unusual for an MCCB and simplifies panel thermal calculations.
The closest functional peer in the SENTRON 3VA family is the 3VA1110-5ED32-0AA0. Both are 3-pole MCCBs with electronic trip units, but the 3VA1110 series is a physically smaller frame (typically 76 mm wide vs. 105 mm) with lower interrupting ratings — it won't match the 242 kA at 240 V that this 3VA2040 frame delivers. If your panel was specified around the 3VA1110-5ED32-0AA0, the 3VA2040-6HL32-0AA0 will not drop in without rewiring: the wider footprint and different mounting hole pattern mean a new drill template. Use the 3VA2040 when you need the higher fault-interrupt capacity or the flat 40 A thermal curve; stay with the 3VA1110 if panel space is tight and fault current is lower.
