Siemens 50MA3HJE Control Station

Siemens 50MA3HJE is a three-operator, 50 Series standard-duty pushbutton control station designed for 600 V AC circuits up to 5 A. The assembly includes three momentary pushbuttons—OPEN, CLOSE, and STOP—each providing one normally open and one normally closed contact (1NO-1NC), enabling straightforward control logic from a single panel point. With a NEMA 1 enclosure rating, the station is intended for indoor, non-hazardous environments and is suitable for panel mounting in a variety of industrial applications such as conveyors, hoists, and presses where clear open/close/stop signaling is required. Distributor listings note a surface-mount installation option, offering flexible mounting in tighter panel footprints and smaller control enclosures. By staying within Siemens' 50 Series lineup, the 50MA3HJE offers consistent compatibility with other standard 50-series components and replacement parts.
