The TM220 release means the thermal element carries 80 A continuously without nuisance tripping, while the magnetic instantaneous pickup is fixed at a multiple of Iu — typical for motor branch or distribution feeder protection where you need coordination downstream. The 80 A rating holds flat from 40 °C through 50 °C; above that it derates to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. If your enclosure ambient runs hot — say a sealed panel next to a furnace line — account for that 6 A loss at the top end. Dimensions are 101.6 mm wide, 130 mm high, 70 mm deep — a 4-pole MCCB that fits standard SENTRON mounting footprints. Maximum power loss is 19.2 W — useful for thermal calculations in a densely packed panel where every watt counts toward the internal temperature rise.","metaTitle":"Siemens 3VA1180-4GE42-0AA0 SENTRON MCCB, 80 A, 4-Pole, 121 k","metaDescription":"Siemens 3VA1180-4GE42-0AA0 SENTRON molded case circuit breaker, 80 A, 4-pole, TM220 release, 121 kA at 240 V.
