That 50 A holds steady through 50 °C; above that it derates to 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, and 45 A at 70 °C — so if your panel ambient runs hot, size the load side accordingly. Breaking capacity lands at 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's enough headroom for most industrial distribution panels on 400 V class systems, but the 690 V figure means you need to check coordination if feeding a 690 V drive input. The 3VA1050-3ED32-0JA0 measures 70 mm deep, 76.2 mm wide, and 130 mm tall — a standard 3-pole MCCB footprint that drops into a SENTRON distribution board or a separate enclosure with DIN-rail adapter.","metaTitle":"Siemens 3VA1050-3ED32-0JA0 SENTRON MCCB, 50 A, 3-Pole, TM210","metaDescription":"Siemens 3VA1050-3ED32-0JA0 SENTRON molded case circuit breaker, 50 A rated, 3-pole, TM210 release, 75.6 kA at 240 V.
