That steep curve means the 187 kA headline is real only on 240 V line-to-line or 120/240 V split-phase services — above 480 V the rating is a fraction of the peak. Thermal derating is mild: 80 A from 40 °C through 50 °C, then 78 A at 55 °C, 77 A at 60 °C, 75 A at 65 °C, and 74 A at 70 °C. ## Physical fit and auxiliaries The case is 130 mm tall, 76.2 mm wide, and 70 mm deep — a standard 3-pole MCCB footprint that drops onto a DIN rail or mounts directly to a backplate.","metaTitle":"Siemens 3VA1180-5EF32-0AD0 SENTRON MCCB, 80A, 187kA at 240V","metaDescription":"Siemens SENTRON 3VA1180-5EF32-0AD0 molded case circuit breaker, 80A rated at 40°C, 187kA breaking at 240V. 3-pole, TM240 release, 3 aux switches.
