The breaker holds its full 80 A rating from 40 °C through 50 °C ambient; above that it derates linearly to 74 A at 70 °C. In a sealed, uncooled enclosure that hits 55 °C, expect 78 A continuous capacity — factor that into the load schedule. The 70 mm depth and 76.2 mm width fit standard 3-pole MCCB mounting footprints on DIN rail or direct panel-mount, with 130 mm height clearing most distribution board gutters. Maximum power dissipation is 19.2 W at rated load, which matters for thermal rise calculations in multi-breaker panels. The 3-pole construction suits three-phase feeders, branch circuits, and panel main incomers.","metaTitle":"Siemens 3VA1180-3EF36-0AA0 SENTRON MCCB, 80 A, 3-Pole, TM240","metaDescription":"Siemens 3VA1180-3EF36-0AA0 SENTRON 3-pole MCCB, 80 A continuous, TM240 release, 75.6 kA at 240 V.
