Rated 32 A continuous at 40 °C, it holds that full rating through 50 °C before a mild derating curve begins — 31 A at 55 °C, 30 A at 70 °C — so in a well-ventilated 40 °C panel you get the full 32 A without headroom loss. Breaking capacity is the standout number here: 187 kA at 240 V AC, dropping to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. The 17 kA floor at 500/690 V is still adequate for most 690 V industrial distribution. Power loss at rated load is 13.1 W — modest for a 32 A frame, meaning the heat load inside a sealed enclosure stays manageable.
Dimensions: 130 mm height, 76.2 mm width (3 inches), 70 mm depth. The 3-inch width is standard for a 3-pole SENTRON 3VA frame — it occupies the same footprint as other 3VA 3-pole breakers, so swapping between variants in a panel layout requires no busbar or DIN-rail rework. Mounting is via the rear screw terminals; no DIN-rail clip on this frame, so plan for direct panel mounting or a mounting plate.
