Product details

It's rated 50 A continuous at 40 °C, and the thermal curve holds that rating steady up through 50 °C — you only see a slight drop to 49 A at 55 °C, 48 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. Breaking capacity is what you care about for fault duty: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500 V and 690 V. That's a solid interrupting rating for most industrial panel feeds — it'll clear a bolted fault without upstream coordination issues in a typical 480 V distribution. Power loss at full load runs 14.6 W maximum — worth checking if you're packing breakers tight in a sealed enclosure.

If you're swapping into an existing panel that was laid out for a 3VA1010-2ED32-0JA0, the width and depth are the same, so it'll drop in without rewiring the bus bars.
