That means in a warm panel — say 55 °C internal ambient — you lose 8 A per pole; plan the load accordingly if you're pushing the 400 A bus.
At 240 V AC it interrupts 187 kA; at 415/440 V AC it's 121 kA; at 500 V AC it's 76 kA. If your transformer or generator can deliver 150 kA at 480 V, this breaker at 500 V (76 kA) won't be enough; step up to a higher interrupting-rated frame.
The 3-pole frame measures 138 mm wide, 248 mm tall, 110 mm deep — a standard MCCB footprint for 400 A class.
It interrupts 187 kA at 240 V AC, 121 kA at 415/440 V AC, and 76 kA at 500 V AC.

The 3VM1340-5EE32-0AA0 is a 3-pole frame at 138 x 248 x 110 mm; the 3VA1112-5EE32-0AA0 is a different frame size and rating. Panel fit and bus spacing must be verified against the existing cutout and connection layout.
