The 3VA1150-6EF32-0AA0: Interrupting capacity is the headline: 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at both 500 V and 690 V. At 690 V the 17 kA still covers most motor-drive branch circuits. Three-pole, rated insulation voltage 800 V, front IP40 protection. Max power loss 14.6 W, so ventilation in a sealed enclosure is worth checking if you pack multiple breakers.
