The 3VA1132-5EF36-0DC0: The 32 A rating holds steady from 40 °C up to 50 °C ambient, then derates to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C. If you're packing this into a hot enclosure or a panel near a furnace line, that derating curve is what you need to check against your actual load — the breaker won't trip early, but you can't count on the full 32 A above 50 °C. The base switch variant is 3VA11325EF360AA0.
The 3VA1132-5EF36-0DC0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for the SENTRON 3VA frame — it clips onto a DIN rail or mounts with screws to a backplate. The 70 mm depth means it won't stick out past a 100 mm deep enclosure door, so you can fit a standard cover without a bulge.
