Above that, it steps down to 38.4 A at 55 °C and 36 A at 70 °C, so if your enclosure runs hot, check the ambient curve before committing the BOM line.
This MCCB delivers 220 kA at 240 V, 154 kA at 415 V, 121 kA at 440 V, and 17 kA at 690 V. At 690 V the 17 kA rating still covers most motor-drive branch circuits.
The 3VA1140-6EF32-0AE0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The IP40 front protection means it's sealed against tools and fingers on the front face, but the terminals are open for wiring; mount it inside a panel with a door for full IP protection. Four HQ auxiliary switches are built in, so you get status feedback without adding a separate block.
