That's rare; most breakers start dropping at 50 °C. The ETU850 release is a communicating electronic trip unit — it talks to the plant network, so you can pull event logs and set curves remotely.
That 140 mm width is a standard 4-pole MCCB slot — it'll drop into a SENTRON panel base without adapters. The 86 mm depth leaves room behind the door for wiring gutters or a second row of breakers.

Both are 4-pole SENTRON MCCBs in the same 140 mm width footprint, so the physical mounting and bus connections are compatible. The key difference is the trip unit: the 3VA2025-7KP42-0AA0 uses an ETU850 communicating release, while the 3VA2125-8KQ42-0AA0 uses a different electronic trip. Verify the trip curve and communication protocol match your panel's wiring before swapping.
