The 3VA1132-4EF32-0HC0: The 32 A continuous rating holds flat from 40 °C to 50 °C, then 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 121 kA at 240 V means it safely interrupts fault currents up to that level without upstream cascading; at 690 V the same breaker handles 11.9 kA, so verify the available fault current at the point of installation.
The integrated auxiliary trip is order code 3VA9688-0BL30.
The depth is 70 mm.
The width is 76.2 mm.
Yes, it includes a shunt trip (STL) auxiliary release and two high-quality auxiliary switches.
