The interrupting ratings step down from 75.6 kA at 240 V to 11.9 kA at 690 V, so the voltage class of your distribution system decides the available fault current it can clear.
At 415 V it interrupts 52.5 kA; at 440 V, 32 kA; at 500 V and 690 V it drops to 11.9 kA. That makes it a strong choice for 240 V or 415 V panels with high available fault current, but on a 690 V line you need to verify the SCCR of the downstream gear stays under 11.9 kA. Thermal derating is mild through the typical panel ambient range. The 32 A rating holds from 40 °C to 50 °C, then steps to 31 A at 55 °C and 60 °C, and 30 A at 65 °C and 70 °C.
The 3VA1132-3EE36-0AA0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. Power loss at full rated current is 10.6 W maximum. In a dense panel with multiple breakers side by side, that heat adds to the enclosure rise; account for it in the thermal budget rather than assuming zero derating from adjacent units.
