The TM210 thermal-magnetic release handles overloads and short-circuits without external power — no voltage trigger required. The interrupting ratings tell you where it can safely clear a fault: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V. The 80 A rating holds flat from 40 °C to 50 °C; above that it derates gradually to 72 A at 70 °C, so a panel running at 55 °C ambient still carries 76.8 A — useful for a crowded enclosure with minimal ventilation. Mount it inside a panel with a door; do not expose it to washdown or outdoor weather. The 70 mm depth, 76.2 mm width, and 130 mm height fit the standard SENTRON 3VA footprint, so it drops into an existing DIN-rail or screw-mounted assembly without re-drilling the backplate.
Built-in auxiliary and undervoltage release
The undervoltage release (UVR) is also factory-fitted, designed per the 3VA9608-0BB11 auxiliary trip assembly. The UVR is wired separately from the load circuit, so a 24 VDC safety PLC output can drive it directly.
