It carries a rated continuous current Iu of 160 A and delivers interrupting ratings that step down with voltage: 187 kA at 240 V AC, 121 kA at 415 V AC, 76 kA at 440 V AC, and 17 kA at 500 V AC — the 240 V figure is the headline for high-fault panels. The TM220 release provides LI protection (thermal overload Ir adjustable 112–160 A, magnetic fixed at 10 x In).
Ambient temperature derating is already baked into the spec: full 160 A from 40 °C up to 50 °C, then steps down to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. No neutral conductor upgrade or auxiliary contact kit is available on this variant — plan separate neutral and alarm wiring if needed.
