What this MCCB does on the line
Breaking capacity runs 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V — so the available fault current at your service voltage decides whether this frame holds or you step up to a higher-rated 3VA variant.
At 55 °C it derates to 158 A, at 60 °C to 155 A, at 65 °C to 153 A, and at 70 °C to 150 A — so if your panel runs hot (say 55 °C inside the enclosure), you lose 2 A per pole, which matters for a continuous load near the limit.
The 3VA1116-5FF42-0AA0 measures 130 mm high, 101.6 mm wide, and 70 mm deep — a 4-pole MCCB that fits standard DIN-rail or screw-mount panel layouts. The 101.6 mm width (4 inches) is the same as other 4-pole 3VA frames, so swapping between 80 A and 160 A versions in the same panel footprint is straightforward.
What you don't get on this variant
If you need shunt trip, aux contacts, or earth-leakage, you're looking at a different 3VA order code.
