This MCCB delivers 52.5 kA at 240 V, 32 kA at 415 V, 13.6 kA at 440 V, and 7.5 kA at 690 V. The steep drop above 415 V is typical for a compact-frame SENTRON — at 690 V the 7.5 kA rating still covers most motor branch circuits and transformer secondaries in 690 V industrial networks. For a panel originally specified around a 3VA1010-2ED42-0AE0 (a 100 A frame), the 3VA1050-2ED32-0JH0 shares the same 76.2 mm width and 70 mm depth, so it drops into the same DIN-rail or screw-mount footprint without rewiring — provided the lower 50 A continuous rating and the TM210 release curve match the load. Above that it derates linearly: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C. For a panel builder, the 70 mm depth and 76.2 mm width mean the breaker fits standard 4-module (76.2 mm) DIN-rail spacing — no gland-plate modification needed when replacing a similarly sized SENTRON frame.","metaTitle":"Siemens 3VA1050-2ED32-0JH0 SENTRON MCCB, 50 A, 52.5 kA at 24","metaDescription":"Siemens 3VA1050-2ED32-0JH0 SENTRON molded case circuit breaker, 3-pole, 50 A rated, breaking capacity 52.5 kA at 240 V.
