The steep drop above 440 V is the key constraint: if your system fault current exceeds 7.5 kA at 500/690 V, this breaker is not the right choice — step up to a higher interrupting-rated SENTRON frame. At 415 V, the 52.5 kA rating covers most industrial distribution panels with typical transformer sizes up to 2 MVA. The 80 A rating holds flat from 40 °C to 50 °C (–), then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. In a sealed enclosure with multiple breakers ganged, expect the 55–60 °C range — plan for the 77–78 A effective capacity. The 21.7 W maximum power loss is moderate — no forced cooling needed in a ventilated panel, but group several of these in a sealed box and the internal temperature rise will eat into the derating curve.","metaTitle":"Siemens 3VA1080-3ED36-0DA0 SENTRON MCCB, 80 A, 3-Pole, 70 mm","metaDescription":"Siemens SENTRON 3VA1080-3ED36-0DA0 molded case circuit breaker, 80 A at 40 °C, 3-pole, 75.6 kA at 240 V.
