Front protection is IP40, meaning it keeps tools and fingers out but isn't sealed against washdown — panel-mount only, no outdoor exposure. Above that it derates: 48 A at 55 °C, 47 A at 60 °C, 46 A at 65 °C, 45 A at 70 °C. ## Panel fit — dimensions and auxiliaries Footprint is 76.2 mm wide × 130 mm high × 70 mm deep — standard 3-pole MCCB width for a 50 A frame, mounts on a DIN rail or direct panel. The four HQ auxiliary switches (2 NO + 2 NC) are wired at the factory; no add-on kit needed. No communication module either; this is a standalone breaker.","metaTitle":"Siemens 3VA1050-4ED36-0AE0 SENTRON MCCB, 50 A, 121 kA at 240","metaDescription":"Siemens 3VA1050-4ED36-0AE0 SENTRON molded case circuit breaker, 3-pole, 50 A rated continuous current, 121 kA breaking at 240 V.
