It is a 3-pole device carrying a breaking capacity of 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V — numbers that define its fault-interruption capability at each voltage level, not just a single headline figure. The 32 A rating holds across ambient temperatures up to 50 °C; above that it derates gradually to 28.8 A at 70 °C, which matters for panels running warm near the top of the enclosure.
The 3VA1132-3EF32-0AF0 measures 76.2 mm wide, 130 mm high, and 70 mm deep — a standard 3-pole MCCB footprint that fits most DIN-rail or panel-mount enclosures without re-drilling. Front IP40 protection covers the operator interface; the rest of the device is designed for enclosed panel mounting.
For a site electrical engineer working on selectivity: the TM240 trip unit is fixed (not adjustable), so coordination with downstream breakers depends on the time-current curve of this specific thermal-magnetic release.
