Line protection MCCB — 50 A, 3-pole, TM210 release
The 3-pole design with IP40 front protection suits panel-mount installations where the breaker is accessible but the bus is enclosed.
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.
