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. That 220 kA figure at 240 V means it handles high-fault utility feeds without cascading upstream — useful for main breaker positions in industrial switchboards. At 690 V the 17 kA still covers most motor-drive branch circuits. Three-pole, rated insulation voltage 800 V, front IP40 protection. Dimensions are 70 mm deep, 76.2 mm wide, 130 mm tall — fits standard MCCB mounting footprints in Siemens SENTRON panels or third-party enclosures with the same cutout. Max power loss 14.6 W, so ventilation in a sealed enclosure is worth checking if you pack multiple breakers.
