It carries an interrupting capacity of 75.6 kA at 240 V, stepping down to 52.5 kA at 415 V and 11.9 kA at 690 V — so it's sized for high-fault industrial distribution panels where the available short-circuit current is substantial. Above that it begins to taper: 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C (–). The maximum power loss of 19.2 W is moderate for a 3-pole 80 A frame; it won't cook a small panel but it's not negligible either. Plan for some airflow if the ambient inside the enclosure runs above 50 °C. That 76.2 mm width is a standard 3-pole MCCB footprint — three modules at 25.4 mm each — so it drops into a typical DIN-rail or panel-mount cutout without surprises. It ships with one auxiliary switch and one trip alarm switch, which is useful for remote status monitoring without adding a separate accessory module.","metaTitle":"Siemens 3VA1180-3EF32-0AG0 SENTRON MCCB, 80 A, 3-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1180-3EF32-0AG0 molded case circuit breaker, 80 A, 3-pole, 75.6 kA interrupting at 240 V.
