Rated current holds at 80 A up to 50 °C, then derates linearly to 74 A at 70 °C — a 7.5 % drop from the 40 °C baseline. That derating matters when the breaker shares a crowded enclosure with other heat sources; the panel designer should account for the actual ambient at the mounting location. Short-circuit ratings drop with system voltage: 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at both 500 V and 690 V. The 690 V figure is the same as the 500 V rating, which is unusual — verify the coordination study if the breaker is applied at 690 V, as the margin between available fault current and the 7.5 kA limit may be tight. Depth of 70 mm leaves clearance for rear-access wiring and shunt-trip wiring without crowding the gland plate.","metaTitle":"Siemens 3VA1080-3ED36-0HA0 SENTRON MCCB, 80 A, 3-Pole, Shunt","metaDescription":"Siemens SENTRON 3VA1080-3ED36-0HA0 molded case circuit breaker, 80 A rated at 40 °C, 3-pole, 75.6 kA at 240 V, shunt trip release.
