Its interrupting capacity reaches 121 kA at 240 V AC, dropping to 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V — meaning it handles high-fault scenarios at lower voltages while still clearing substantial faults at distribution-level 690 V.
At 55 °C it derates to 31 A, at 65 °C to 30 A, and holds 30 A through 70 °C — no steep cliff, so a panel running warm still gets most of the capacity. Dimensions are 130 mm height, 76.2 mm width, 70 mm depth; it mounts on a DIN rail or panel plate in a standard SENTRON 3VA footprint. Power loss is 13.1 W maximum, which matters for enclosure thermal calculations when grouping several breakers.
The TM240 thermal-magnetic release provides fixed thermal pickup (for overload protection) and magnetic instantaneous trip (for short-circuit protection) — no adjustment dials, which simplifies specification but means the trip curve is fixed. No ground-fault monitoring module is included; if GFP is needed, an external module or a different 3VA variant with that option would be required. The UVR is an undervoltage release, not a shunt trip — it trips when voltage falls below a set level, not when a control signal is applied.
