At 55 °C the continuous current derates to 76.8 A, dropping to 72 A at 70 °C. For panel builders, this means the 80 A frame can be applied at full rating in a 50 °C enclosure; above that, the load or the breaker must be downsized per the published curve. The 3VA1080-4ED32-0AD0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. The 76.2 mm width (3 inches) is the standard 3-pole MCCB footprint for this frame size, so it drops into existing SENTRON 3VA panel cutouts without modification. ## Auxiliary contacts and release configuration This variant ships with three auxiliary switches (HQ type) for remote status indication. The auxiliary contacts share the same compact housing; no additional side-mount modules are required for the three-switch configuration.","metaTitle":"Siemens 3VA1080-4ED32-0AD0 SENTRON MCCB, 80 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1080-4ED32-0AD0 molded case circuit breaker, 80 A rated, 121 kA breaking at 240 V, TM210 release, 3-pole line protection.
