Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V, and still holds 7.5 kA up to 690 V — serious SCCR headroom for industrial panels where fault current is high.
Rated 100 A from 40 °C to 50 °C, then it starts to pull back: 98 A at 55 °C, 96 A at 60 °C, 94 A at 65 °C, 91 A at 70 °C. If your panel ambient sits above 50 °C, factor the derating into your load schedule. The TM120M release is fixed — no interchangeable trip units — so what you see on the nameplate is what you get. Insulation voltage rated 800 V, which covers most 480/600 V systems with margin.
That means you can spec it into a new BOM without worrying about a last-time-buy window.
Width 76.2 mm (3 in), height 130 mm (5.12 in), depth 70 mm (2.76 in). Three-pole footprint leaves room for side-mounted accessories; no undervoltage release or shunt trip on this variant — verify if your safety circuit needs one. Front IP40, suitable for enclosed panel use, not open washdown.
