The TM210 thermal-magnetic release handles overloads and short-circuits without external power, and the integrated undervoltage release (UVR) drops the breaker if control voltage is lost — a standard requirement for emergency-stop circuits and safety disconnects. Breaking capacity runs from 121 kA at 240 V down to 11.9 kA at 690 V, so at typical 400/415 V distribution levels it clears 75.6 kA without cascading upstream breakers.
Thermal derating and panel space
Physical footprint is 130 mm high, 76.2 mm wide, 70 mm deep; the 3-pole width (about 3 inches) fits standard panel layouts.
Auxiliary contacts and release configuration
The undervoltage release is wired separately from the TM210 trip mechanism; on a loss of control voltage the UVR trips the breaker mechanically. The integrated auxiliary trip order code is 3VA9608-0BB11 if you need a replacement module.
