Front protection is IP40; the unit is sized for DIN-rail or panel-mount integration at 70 mm deep, 76.2 mm wide, 130 mm tall.
Interrupting capacity and thermal derating
Interrupting capacity is 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V — these are the maximum fault currents the breaker can safely clear at each voltage level. The TM210 release holds 50 A continuous up to 50 °C ambient; above that it derates to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.
