Rated breaking capacity reaches 52.5 kA at 240 V, 32 kA at 415 V, and 13.6 kA at 440 V, with a floor of 7.5 kA at 500 V and 690 V. Continuous current holds at 80 A 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. The overcurrent release is the TM210 thermal-magnetic type, so the thermal element tracks ambient temperature — a panel running near 70 °C loses about 7.5 % of the nominal rating. Width is 101.6 mm (4 in), depth 70 mm (2.76 in), height 130 mm (5.12 in). Insulation voltage rated 800 V, so it suits 690 V line-to-line systems with margin.","metaTitle":"Siemens 3VA1080-2ED42-0CA0 SENTRON MCCB, 80 A, 4-Pole, 52.5","metaDescription":"Siemens SENTRON 3VA1080-2ED42-0CA0 molded case circuit breaker, 80 A thermal rating, 4-pole, breaking capacity 52.5 kA at 240 V.
