The 3-pole breaker delivers a breaking capacity of 187 kA at 240 V AC and 121 kA at 415 V, making it suitable for high-fault-current industrial mains or feeder circuits. The 800 A rating holds flat from 40 °C to 50 °C, then derates linearly to 722 A at 70 °C. For a panel that runs at 55 °C ambient, the usable current is 780 A — enough headroom for most 600 A feeder designs. Dimensions are 320 mm high × 210 mm wide × 120 mm deep.","metaTitle":"Siemens 3VA1580-5EF32-0BC0 SENTRON MCCB, 800 A, 3-Pole, 187","metaDescription":"Siemens SENTRON 3VA1580-5EF32-0BC0 molded case circuit breaker, 800 A rated at 40 °C, 3-pole, 187 kA breaking at 240 V.
