Three poles, rated continuous current holds at 400 A from 40 °C up through 50 °C, then derates to 385 A at 55 °C, 370 A at 60 °C, 355 A at 65 °C, and 340 A at 70 °C — so a panel that runs warm needs to account for the drop above 50 °C ambient. Interrupting capacity scales with system voltage: 242 kA at 240 V, 187 kA at 415 V and 440 V, 121 kA at 500 V, and 7.5 kA at 690 V.
Sourcing and lifecycle — active, quoted to order
If you are cross-referencing an older panel design that used a different SENTRON frame, the 3VA2340-6HN32-0DH0 carries the same 3-pole 400 A rating and UVR provision — but verify the auxiliary switch count and the physical cutout against your existing backpanel layout before committing.
Auxiliary configuration and trip indication
Power loss at full rated current is 98.5 W maximum. That heat has to leave the enclosure — factor it into your thermal budget if the panel is sealed or tightly packed.
