Thermal performance holds 800 A flat from 40 °C through 60 °C, then derates to 767 A at 65 °C and 703 A at 70 °C — a curve that matters when this breaker sits in a warm switchboard or a non-air-conditioned enclosure. ## Panel fit and mounting constraints The 3VA2580-7MQ32-0AA0 measures 320 mm high, 210 mm wide, and 120 mm deep — a 3-pole frame that bolts into a standard MCCB cutout on a backplate or DIN-rail adapter.","metaTitle":"Siemens SENTRON 3VA2580-7MQ32-0AA0 MCCB, 800 A, 3-Pole, Moto","metaDescription":"Siemens 3VA2580-7MQ32-0AA0 SENTRON molded case circuit breaker, 800 A rated, 3-pole, motor protection version with ETU860M trip unit.
