The 3VA1025-4ED32-0AD0: The interrupting ratings tell the real story here: 121 kA at 240 V, 75.6 kA at 415 V, and still 11.9 kA at 690 V. That's high-fault capacity for a 25 A frame — it clears a bolted fault upstream without cascading to the main breaker, which is the key selectivity requirement in a 480 V industrial panel.
Rated current holds flat at 25 A from 40 °C through 50 °C, then derates to 24 A at 55 °C and 23 A at 70 °C. Power loss is 8.5 W maximum. For a 25 A MCCB that's modest — it won't drive up internal panel temperature noticeably, but if you're packing six of these side-by-side in a small enclosure, the cumulative 51 W needs to be in your thermal calculation.
The 3VA1025-4ED32-0AD0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 70 mm depth includes the arc chamber; verify clearance to the enclosure door for the rotary handle if used.
