Its interrupting capacity hits 121 kA at 240 V, 75.6 kA at 415 V, and 52.5 kA at 440 V — numbers that govern selectivity and SCCR headroom in a distribution panel. The 70 mm depth and 76.2 mm width fit standard SENTRON 3VA mounting footprints, so it swaps into an existing 3VA panel bus without re-drilling the gland plate. ## Thermal derating and release behavior Above that, it derates to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. ## Auxiliary contacts and enclosure protection","metaTitle":"Siemens 3VA1080-4ED32-0AF0 SENTRON MCCB, 80 A, 121 kA at 240","metaDescription":"Siemens SENTRON 3VA1080-4ED32-0AF0 molded case circuit breaker, 80 A rated, 121 kA interrupting at 240 V, 3-pole, TM210 release.
