The 80 A rating holds steady up to 50 °C; above that it derates to 76.8 A at 55 °C and 72 A at 70 °C. The 3VA1080-2ED42-0BH0 measures 130 mm high, 101.6 mm wide, and 70 mm deep — a standard MCCB footprint for panel-mounting on a DIN rail or direct screw-fix.","metaTitle":"Siemens 3VA1080-2ED42-0BH0 SENTRON MCCB, 80 A, 4-Pole, Line","metaDescription":"Siemens SENTRON 3VA1080-2ED42-0BH0 molded case circuit breaker, 80 A rated current, 4 poles, 52.5 kA at 240 V.
