Its breaking capacity hits 220 kA at 240 V, 154 kA at 415 V, and 121 kA at 440 V — so it handles high-fault utility feeds and transformer secondaries without cascading upstream. That keeps the BOM simple but means you size the breaker to the load, not the other way around. The shunt trip (STL) and two HQ auxiliary switches come integrated, saving a panel-builder the labor of snapping on add-on modules later.
The 3VA1132-6EF32-0KC0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep. The 76.2 mm width (three 25.4 mm pole pitches) matches the standard SENTRON 3VA mounting footprint, so swapping into an existing 3VA panel cutout is a straight drop-in.
At 55 °C it derates to 30.72 A, at 60 °C to 30.08 A, at 65 °C to 29.44 A, and at 70 °C to 28.8 A. That's a gentle slope — about 3.2 A lost over the full 30 °C rise — so a 30 A continuous load at 60 °C still has headroom. The TM240 release's thermal element tracks this curve, so no manual adjustment needed.
