Rated current holds at 16 A from 40 °C up to 55 °C, then derates to 15 A at 60 °C through 70 °C — so in a warm panel you lose 1 A, not a full trip curve shift. Interrupting rating drops as voltage rises: 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 500 V and 690 V. That 17 kA floor at 690 V is the number to check if your system runs at 480/277 V or 600 V class; the 187 kA at 240 V is for the low-voltage side of a step-down transformer. Power loss at rated load is 13.1 W — negligible for panel heat budget but worth noting if you're packing ten of these in a small enclosure.
Panel fit and environment
Dimensions: 130 mm high, 76.2 mm wide (3 inches), 70 mm deep. That 3-inch width per pole is standard for SENTRON 3VA MCCBs — it fits the same DIN-rail or panel-mount footprint as the rest of the 3VA family.
