That 160 A holds flat through 50 °C; above that the thermal curve steps down to 153.6 A at 55 °C and 144 A at 70 °C, so if this breaker lives in a hot enclosure near other heat sources, you need to account for that derating on the load side. The TM210 overcurrent release handles the thermal-magnetic trip — fixed thermal and magnetic elements, no electronic adjustment. Line protection version means it's set up for feeder and distribution duty, not motor or generator protection.
Mounting and integration — fits a standard panel footprint
Width is 76.2 mm. Depth of 70 mm and height of 130 mm mean it clears most gland plates and back panels without interference. IP40 on the front keeps dust out of the mechanism. Comes with 2 auxiliary switches (HQ type) and an undervoltage release (UVR) integrated.
