The 3VA1125-3ED26-0AA0: A 2-pole construction with a TM210 thermal-magnetic release (fixed instantaneous pickup at 320 A) and a rated insulation voltage of 500 V. Breaking capacity hits 75.6 kA at 240 V and 52.5 kA at 415 V — sufficient for high-fault utility feeds in commercial and light industrial panels.
Depth is 70 mm (2.76 in), height 130 mm (5.12 in).
Rated 25 A continuous at 40 °C through 50 °C, 2-pole, with a TM210 thermal-magnetic release. Breaking capacity is 75.6 kA at 240 V and 52.5 kA at 415 V. Rated insulation voltage is 500 V.

Both are 2-pole SENTRON MCCBs with the same 50.8 mm width and 70 mm depth, so the mechanical footprint is identical. The key difference is the release: the 3VA1125-3ED26-0AA0 uses a TM210 thermal-magnetic release with fixed instantaneous at 320 A, while the 3VA1020-3ED36-0AA0 uses a different release variant. Check the release curve and the 25 A vs lower current rating before swapping — the panel cutout and wiring space are the same.
