The TM240 thermal-magnetic release handles overload and short-circuit trip curves, and the interrupting ratings are substantial: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. The 70 mm depth, 101.6 mm width, and 130 mm height put it in a standard SENTRON 3VA frame size that bolts into a panel or mounts on a mounting plate.
The 25 A rating holds from 40 °C up to 50 °C; at 55 °C it derates to 24 A, and at 70 °C it's 23 A. The insulation voltage is rated 800 V, and the operating range is -25 °C to 70 °C, with storage from -40 °C to 80 °C.
