Three poles, rated insulation voltage 800 V. The 160 A rating holds from 40 °C through 50 °C; it derates to 158 A at 55 °C, 155 A at 60 °C, 153 A at 65 °C, and 150 A at 70 °C. Breaking capacity drops as voltage rises: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. For a 480 V panel (common in North America) the relevant figure is the 440 V rating — 75.6 kA — which covers most industrial service-entrance requirements. At 690 V the 17 kA rating means this breaker is suited for secondary-side distribution, not main incoming. The shunt trip is what you order when a safety circuit or E-stop needs to open the breaker electrically.
Width 76.2 mm (3 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). That 76.2 mm width is standard for a 3-pole SENTRON 3VA frame — it drops into the same DIN-rail or mounting-plate footprint as the 3VA1112 and 3VA1110 siblings. No rewiring or bus-bar repositioning needed if you are swapping within the same family.
