It carries 80 A continuously at 40 °C across all three poles, with a slight thermal derating curve: 78 A at 55 °C, 75 A at 65 °C, and 74 A at 70 °C — so in a warm enclosure you lose about 6 A off the nameplate before you hit the 70 °C operating max. The interrupting ratings climb with available fault current: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V.
Auxiliary complement and undervoltage release
The auxiliary switch complement lets a PLC or DCS read the breaker's open/closed and tripped status without adding external relays.
Panel fit and footprint
The 3VA1080-3ED32-0CH0 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. If you are swapping into an existing SENTRON or older 3VL cutout, verify the mounting depth: 70 mm leaves clearance for rear-access bus bars or cable ladders behind the breaker.
