The 3VA1132-3EF32-0HH0: Rated continuous current Iu is 32 A, and the breaker holds that rating from 40 °C through 50 °C ambient. Above 55 °C it steps down: 30.72 A at 55 °C, 30.08 A at 60 °C, 29.44 A at 65 °C, 28.8 A at 70 °C. If your panel ambient runs hot — say a sealed enclosure near a furnace line — you lose roughly 1 A per 5 °C above 50 °C. The rated insulation voltage Ui of 800 V covers 480 V and 600 V class systems with margin. The shunt trip (STL) auxiliary release (design per 3VA9688-0BL30) lets a remote signal or emergency-stop circuit open the breaker independently of the overcurrent mechanism.
Physical integration
The breaker measures 70 mm deep, 76.2 mm wide, and 130 mm tall. Operating temperature range is -25 °C to 70 °C, storage from -40 °C to 80 °C.
