The 75.6 kA breaking capacity at 240 V and 52.5 kA at 415 V give this MCCB headroom for high-fault installations, typically found on transformer secondaries or large motor control centers. The 32 kA rating at 440 V and 7.5 kA at 690 V define the upper voltage limits for fault interruption. ## Thermal derating and ambient range The 80 A rating holds steady from 40 °C through 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. Panel builders should account for the 19.2 W maximum power loss when calculating enclosure heat rise. The 3-pole footprint matches standard Siemens 3VA panel cutouts and busbar spacing. The shunt trip (STL) and two auxiliary switches are factory-installed, so no field assembly of accessories is needed.","metaTitle":"Siemens 3VA1080-3ED36-0JC0 SENTRON MCCB, 80 A, 75.6 kA","metaDescription":"Siemens 3VA1080-3ED36-0JC0 SENTRON molded case circuit breaker, 80 A rated at 40 °C, 75.6 kA breaking at 240 V.
