Interrupting capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and still holds 52.5 kA at 440 V — numbers that give you serious SCCR headroom in a 100 A frame without stepping up to a bigger case size. Current rating holds flat at 100 A from 40 °C through 50 °C, then tapers to 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C. Four auxiliary switches (HQ type) come built in.
The 76.2 mm width is the standard 3-pole MCCB footprint — it drops into the same cutout as other SENTRON 3VA frames, so swapping a 3VA1010 or 3VA1110 variant means no re-drilling the backplate.
