The 80 A rating holds flat from 40 °C to 50 °C, then derates to 76.8 A at 55 °C, 75.2 A at 60 °C, 73.6 A at 65 °C, and 72 A at 70 °C — so in a warm enclosure you lose about 10 % of the headroom by 70 °C. Breaking capacity is 75.6 kA at 240 V, 52.5 kA at 415 V, 32 kA at 440 V, and 7.5 kA at 690 V; that 75.6 kA at 240 V covers high-fault utility feeds, while the 7.5 kA at 690 V is the limit for 690 V line-side faults. ## Deployment context and panel fit Dimensions are 101.6 mm wide, 130 mm high, and 70 mm deep — the 101.6 mm width is a standard 4-pole MCCB footprint, so it fits existing cutouts or busbar spacing in most distribution boards. Front protection is IP40 (finger-safe, no water ingress), suitable for indoor panel mounting.","metaTitle":"Siemens 3VA1080-3ED42-0DA0 SENTRON MCCB, 80 A, 4-Pole, 75.6","metaDescription":"Siemens SENTRON 3VA1080-3ED42-0DA0 molded case circuit breaker, 80 A, 4-pole, line protection, 75.6 kA at 240 V.
