The interrupting capacity drops as voltage rises: 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. If it's 60 kA at the same voltage, you need a higher-rated frame or upstream current-limiting fuse — the SCCR at the equipment level must stay at or below the breaker's rating.
In a crowded panel with multiple breakers side by side, ambient temperature inside the enclosure can easily hit 55–60 °C — so that 38.4 A or 37.6 A effective rating is the real-world limit, not the 40 A on the label.

75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. The TM210 release provides thermal-magnetic protection for line-feeder applications.
Not directly — the 3VA1010-2ED32-0JA0 is a different frame rating and release variant. Both are 3-pole SENTRON MCCBs with the same 70 mm depth, but the 3VA1040-3ED32-0DA0 carries a 40 A TM210 release versus the 3VA1010's lower rating. Verify the bus-bar spacing and line/load lug centers against the panel layout before swapping.
