Breaking capacity runs from 75.6 kA at 240 V down to 10.5 kA at 690 V, which covers most industrial low-voltage distribution scenarios.
Ratings that matter for your BOM line
The 160 A rating holds flat from 40 °C up to 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. That's a shallow derate curve — you lose only 10 % at the top of the operating range, so it's a solid pick for a warm enclosure. The interrupting ratings are: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. Those numbers govern fault-clearing capability at the available fault current on your secondary side. The integrated auxiliary release is a shunt trip (STL) — order code 3VA9688-0BL32 if you need the matching accessory.
Footprint is 70 mm deep, 76.2 mm wide, 130 mm tall — a 3-pole MCCB that fits a standard panel-mount cutout. The shunt trip release is built in, not a field-installed kit, which saves panel-build labor.
