If your panel runs hot near a drive or transformer, size the branch load for the derated figure at the actual ambient. The 3VA1050-4ED32-0AD0 measures 130 mm high, 76.2 mm wide, and 70 mm deep. That 76.2 mm width (3-inch footprint) is standard for 3-pole 50 A MCCBs in the SENTRON range — it fits the same mounting slots as the 3VA1010-2ED32-0JA0 without rewiring or bus-bar repositioning. The IP40 front means the breaker face can be exposed in a dead-front panel; no additional cover is needed for the operator handle.","metaTitle":"Siemens 3VA1050-4ED32-0AD0 SENTRON MCCB, 50 A, 3-Pole, 121 k","metaDescription":"Siemens 3VA1050-4ED32-0AD0 SENTRON molded case circuit breaker, 50 A continuous, 3-pole, 121 kA at 240 V.
