Its breaking capacity hits 121 kA at 240 V and 75.6 kA at 415 V, so it handles high-fault utility feeds without cascading upstream.
The 80 A rating holds flat through 50 °C ambient; above that it steps down to 76.8 A at 55 °C and 72 A at 70 °C. The 76.2 mm width and 70 mm depth fit a standard 3-pole MCCB footprint on the DIN rail or panel-mount backplate — no surprises swapping into an existing SENTRON or 3VA cutout.

The 3VA1010-2ED32-0JA0 is a lower-current sibling in the same SENTRON 3VA family. It shares the same frame size, TM210 release design, and 3-pole configuration, but its continuous rating and breaking capacities differ. Verify the load current and fault level before substituting — the 3VA1080-4ED32-0KA0 carries 80 A and 121 kA at 240 V, which the 3VA1010-2ED32-0JA0 may not match.
Width is 76.2 mm, depth is 70 mm, height is 130 mm — standard 3-pole MCCB envelope for DIN-rail or panel-mount installation.
