The TM210 overcurrent release combines a thermal bimetal for overload protection and a magnetic coil for short-circuit response. Interrupting capacity reaches 75.6 kA at 240 V AC and 52.5 kA at 415 V AC — figures that cover most industrial service-entrance and distribution panel fault levels without cascading upstream.
The IP40 front protection suits enclosed panel mounting.
Both are 2-pole SENTRON 3VA frame MCCBs sharing the same 70 mm depth, 50.8 mm width, and 130 mm height — mechanical fit is identical. The difference is the release and rating: this one uses a TM210 thermal-magnetic release rated 20 A, while the 3VA1110-5ED32-0AA0 carries a different trip curve and amperage. Check the load-side conductor sizing and coordination study before swapping.
