Siemens 3VA1180-4ED32-0KF0 — 80 A SENTRON MCCB for Line Protection
It carries a rated current of 80 A continuous at 40 °C, 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 — so in a warm enclosure the breaker still delivers nearly full rating, but you need to check the ambient at the mounting location if you're loading it near 80 A. Interrupting capacity is the headline number here: 121 kA at 240 V AC, 75.6 kA at 415 V, 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V.
Integration — Panel Fit and Accessories
Dimensions are 130 mm height, 76.2 mm width, 70 mm depth — a standard 3-pole MCCB footprint that mounts on a DIN rail or directly to a backplate.
