Breaking capacity steps down with system voltage: 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. Above that it derates: 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C. ## Integrated auxiliary releases and switching The integrated auxiliary trip is order code 3VA9608-0BB25. The UVR drops the breaker if control voltage falls below its dropout threshold — useful for safety circuits or upstream undervoltage protection schemes. The 101.6 mm width is a standard 4-pole MCCB footprint — it occupies four 25.4 mm (1-inch) module positions on a DIN rail or direct panel mount. Front IP40 protection means it is splash-proof from the front but not sealed for washdown; keep it inside a closed enclosure. The trip indicator is visible through the front cover, so a quick walk-by inspection shows tripped vs. healthy status without opening the panel door.","metaTitle":"Siemens 3VA1080-2ED42-0DH0 SENTRON MCCB, 80 A, 4-Pole, TM210","metaDescription":"Siemens 3VA1080-2ED42-0DH0 SENTRON molded case circuit breaker, 80 A rated continuous current, 4 poles, TM210 release, 52.5 kA at 240 V.
