The breaking capacity tells the real story: 187 kA at 240 V, 121 kA at 415 V, 75.6 kA at 440 V, and 17 kA at both 500 V and 690 V. At 690 V the 17 kA figure still covers most industrial distribution scenarios, but if your system fault level exceeds that, you need a higher-rated frame upstream. Thermal derating is worth noting: it holds 80 A flat from 40 °C through 50 °C, then drops to 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. ## Panel integration The 3VA1180-5EF32-0AA0 measures 76.2 mm wide, 130 mm tall, and 70 mm deep — a 3-pole MCCB that fits Siemens standard mounting plates and busbar systems.","metaTitle":"Siemens 3VA1180-5EF32-0AA0 SENTRON MCCB, 80 A, 3-Pole, TM240","metaDescription":"Siemens 3VA1180-5EF32-0AA0 SENTRON molded case circuit breaker, 80 A at 40 °C, 3-pole, TM240 thermal-magnetic trip, 187 kA at 240 V.
