The TM210 thermal-magnetic trip unit provides fixed thermal and magnetic settings — no field adjustment, which simplifies specification but means the breaker must be selected for the exact load profile. Interrupting capacity runs 75.6 kA at 240 V, 52.5 kA at 415 V, and 11.9 kA at 690 V, giving solid fault-clearing headroom across common low-voltage networks.
Above 50 °C the curve steps down: 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Interrupting capacity drops with system voltage as expected. At 415 V (common 3-phase distribution in Europe and Asia) the breaker clears 52.5 kA symmetrically.
The 4-pole width (101.6 mm) is standard for this frame size; verify the existing panel cutout and busbar spacing if retrofitting into an enclosure originally wired for a different MCCB family.
