Above that, the breaker derates linearly: 49 A at 45 °C, 47 A at 50 °C, 46 A at 55 °C, 44 A at 60 °C, 43 A at 65 °C, and 41 A at 70 °C. Dimensions: 75.1 mm deep, 50.8 mm wide, 129.4 mm high. The 50.8 mm width is a standard 2-inch footprint for a 2-pole MCCB — it fits a typical DIN-rail or panel-mount cutout without surprises. Front-face protection is IP40, so it's suitable for a dry indoor enclosure but not washdown areas. The product carries a UL file designation SEAB, indicating UL 489 listing for molded-case circuit breakers.","metaTitle":"Siemens 3VA4150-4ED24-0AA0 SENTRON MCCB, 2-Pole, 50 A, 65 kA","metaDescription":"Siemens 3VA4150-4ED24-0AA0 SENTRON molded-case circuit breaker. 2-pole, 50 A at 40 °C, 65 kA at 240 V interrupting capacity.
