The 187 kA breaking capacity at 240 V AC drops to 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at 690 V; that 240 V figure is the headline for North American 277/480 V wye panels where the line-to-neutral fault current can be high. The thermal derating curve is published: full 100 A up to 50 °C ambient, then 96 A at 55 °C, 94 A at 60 °C, 92 A at 65 °C, and 90 A at 70 °C.
Footprint and panel integration
The 3VA1110-5EE32-0KH0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 76.2 mm width is a standard 3-pole MCCB footprint — it occupies three 25.4 mm (1-inch) module positions on a DIN rail or panel-mount base.
