80 A SENTRON MCCB, 3-pole, TM240 release
The interrupting ratings span the common distribution voltages: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 10.5 kA at 690 V.
Above that, the breaker derates: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C.
Panel footprint and mounting
Width 76.2 mm, height 130 mm, depth 70 mm. That 76.2 mm (3-inch) width is standard for a 3-pole MCCB in this frame size — it occupies three 25 mm module positions on a DIN rail or panel-mount footprint. IP40 on the front face; the enclosure around it must handle the rest of the ingress protection for the assembly.
Shunt trip provision
If the application requires undervoltage or ground-fault protection, a different variant is needed.
