What this 3VA frame carries
It carries an 80 A continuous current rating at 40 °C ambient, with a thermal derating curve that holds 80 A through 50 °C, then steps down to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C.
Breaking capacity across voltage levels
Short-circuit breaking capacity is voltage-dependent: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Built-in undervoltage release and auxiliary switching
A trip indicator is present on the front face, giving a visual flag after a fault trip.
Width of 76.2 mm (3 inches) matches the standard 3-pole MCCB footprint for Siemens 3VA frames; a panel originally cut for a 3VA1110 variant (lower ampacity) shares the same mounting hole pattern and bus-bar spacing, so this 80 A unit drops in without rewiring the bus.
