The 3VA1050-2ED36-0AF0: This breaker's interrupting capacity changes with system voltage, which is typical for MCCBs but easy to miss when you're pulling a BOM from a one-line. At 240 V it clears 52.5 kA; at 415 V it clears 32 kA; at 440 V it clears 13.6 kA; and at 690 V it clears 7.5 kA.
Thermal derating — the real-world current you can actually run
Above that, it starts to taper: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C.
Footprint and panel integration
That width is three standard 25.4 mm pole spacings, so it fits a typical 3-pole MCCB cutout in a distribution panel without surprises.
