Breaking capacity runs 52.5 kA at 240 V, dropping to 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 500/690 V. The 7.5 kA at 690 V is useful for 690 V drives or mining gear, but the real-world SCCR for a standard 400 V panel is the 32 kA number.
Thermal derating — what the 80 A rating actually means
Above 50 °C it begins to step down: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, 74 A at 70 °C.
Physical footprint: 76.2 mm wide (3 in), 130 mm tall (5.12 in), 70 mm deep (2.76 in). That's a standard 3-pole MCCB width — it fits a 3-module-wide DIN-rail or panel-mount cutout. The breaker ships with a basic switch (order code 3VA10802ED360AA0) and accommodates two HQ auxiliary switches.
