At 240 V it interrupts 121 kA; at 415 V that drops to 75.6 kA, then 52.5 kA at 440 V, and 11.9 kA at both 500 V and 690 V. The 80 A rating holds flat from 40 °C through 50 °C, then derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. Depth of 70 mm leaves room behind the panel door for wiring gutters or a second row of breakers. Maximum power loss is 19.2 W at rated current. For a sealed enclosure, that heat must be factored into the thermal rise calculation — at 80 A continuous, the breaker itself dissipates nearly 20 W, which adds to the internal temperature and can accelerate the derating curve if ventilation is poor. The storage limits are wider because the breaker is not carrying current or dissipating heat — handling and shelf life, not running performance. If the application needs shunt trip, UVR, or remote status, a different variant in the 3VA family is required.","metaTitle":"Siemens 3VA1180-4EE32-0AA0 SENTRON MCCB, 80 A, 3-Pole, TM220","metaDescription":"Siemens 3VA1180-4EE32-0AA0 SENTRON molded case circuit breaker, 80 A continuous, 3-pole, TM220 release.
