Ratings and derating
The 3VA1132-5EF36-0DH0: The 32 A rating holds flat from 40 °C to 50 °C ambient, 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. If the panel runs hot — say a sealed enclosure next to a drive cabinet — you lose about 3 A by the time you hit 70 °C. That's predictable and linear; the datasheet curve is clean. The rated insulation voltage Ui is 800 V, so it's comfortable on 480 V and 600 V class systems with margin.
Physical fit and auxiliary options
The can measures 76.2 mm wide, 130 mm tall, and 70 mm deep — standard 3-pole MCCB footprint for the SENTRON 3VA frame. It mounts on a DIN rail or panel-mount via the base, and the front face carries an IP40 protection rating, so it's fine in a clean indoor panel but not washdown areas. The auxiliary contact block is configured as 2 auxiliary switches plus 1 trip alarm switch (HQ version), and there's an undervoltage release (UVR) fitted — the release part number is 3VA9608-0BB25. That UVR means the breaker drops out if control voltage is lost, which is common for emergency-stop circuits or undervoltage protection schemes.
