The TM220 thermal-magnetic release handles overload and short-circuit protection; the 160 A rating holds flat from 40 °C through 50 °C, then derates to 153.6 A at 55 °C, 150.4 A at 60 °C, 147.2 A at 65 °C, and 144 A at 70 °C — so in a warm panel you lose about 10 % of the continuous rating by the time the internal ambient hits 70 °C. The interrupting capacity at 240 V is 187 kA, at 415 V it is 121 kA, at 440 V it is 75.6 kA, and at 690 V it drops to 17 kA.
Built-in undervoltage release — no separate module to source
That means you do not need to buy a separate UVR module and snap it on; the release is part of the breaker.
