The TM210 designation means the thermal trip is fixed at the breaker's frame rating — no interchangeable trip units — so the interrupting capacity is what you get at the terminals: 76 kA at 240 V, 53 kA at 415 V, 32 kA at 440 V, and 8 kA at 500 V.
Thermal derating — what the temperature row means for your panel
If your panel runs at 50 °C with a 25 A load, this breaker holds without nuisance tripping.
The 3VM1025-3ED42-0AA0 measures 70 mm deep, 101.6 mm wide, and 130 mm tall. The 101.6 mm width — exactly 4 inches — is the standard footprint for a 4-pole SENTRON 3VM frame, so it drops into existing panel cutouts and bus-bar layouts without re-drilling.
