Breaking capacity runs from 75.6 kA at 240 V down to 7.5 kA at 690 V — that 75.6 kA figure at 240 V means it can interrupt very high fault currents on low-voltage distribution, typical for transformer secondaries or large bus risers. The TM210 thermal-magnetic trip handles overloads (thermal bimetal) and short-circuits (magnetic coil) in one package — no separate electronic trip unit to program or power.
Thermal derating — the real-world current
At 55 °C it derates to 48 A, at 60 °C to 47 A, and at 70 °C to 45 A.
Auxiliary and undervoltage release
The integrated auxiliary trip is order code 3VA9608-0BB25 — if you're replacing just the aux block, that's the spare part number.
That 101.6 mm width is exactly 4 module spaces on a standard DIN rail — it clips onto the rail and locks in place. Front protection is IP40, so it's splash-resistant from the front but not sealed for washdown.
