The 3VA1132-3EF32-0BC0: Rated short-circuit breaking capacity varies with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V. These figures let you size the breaker for the available fault current at the panel's service voltage — the 240 V rating covers most North American 120/208 V or 277/480 V wye secondary faults, while the 415 V and 440 V ratings suit European 400 V grids. The thermal-magnetic trip holds a flat 32 A from 40 °C through 50 °C ambient; above that it derates to 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, and 28.8 A at 70 °C.
The 70 mm depth leaves clearance for rear-mounted busbars or cable ducts in a typical 200 mm deep enclosure.
