The 220 kA at 240 V is the highest interrupting rating on this breaker, typical for the main breaker position in a 240 V delta or 208Y/120 V panel where available fault current can exceed 100 kA. At 415 V it's 154 kA, and at 440 V it's 121 kA — these cover European and Asian 400 V class networks. The drop to 17 kA at 500 V and 690 V is expected for a 50 A frame; above 480 V the arc extinction becomes more demanding, so the breaker is still usable on 600 V class systems but you need to verify the available fault current at the point of common coupling stays under 17 kA. Temperature derating is minimal up to 50 °C — the breaker holds 50 A. At 55 °C it drops to 49 A, at 60 °C to 48 A, at 65 °C to 46 A, and at 70 °C to 45 A. The 3VA1150-6GF46-0AA0 measures 70 mm deep, 101.6 mm wide, and 130 mm tall. The 101.6 mm width (4 inches) is standard for a 4-pole MCCB in the SENTRON 3VA frame — it occupies four 25 mm (1-inch) pole positions on a DIN rail or panel-mount backplate. Maximum power loss is 14.6 W, which is modest for a 50 A breaker; no forced ventilation required in a typical IP40 enclosure.","metaTitle":"Siemens 3VA1150-6GF46-0AA0 SENTRON MCCB, 50 A, 4-Pole, 220 k","metaDescription":"Siemens 3VA1150-6GF46-0AA0 SENTRON molded case circuit breaker, 50 A rated, 4-pole, line protection, TM240 release.
