Siemens 50MA3HJE Pushbutton Control Station

Siemens 50MA3HJE is a three‑button standard‑duty pushbutton control station from the 50 Series, designed as a complete surface‑mount block for panel installations. This three‑operator assembly includes momentary pushbuttons labeled OPEN, CLOSE, and STOP; two of the switches provide 2 NO/2 NC contacts and a third uses 1 NO/1 NC with a common jumper (50ZAC1), enabling straightforward sequencing of start/stop logic. Rated for up to 600 VAC and 5 A, the station is built for indoor control circuits in a NEMA 1 enclosure, reflecting Siemens’ Class 50 standard‑duty construction for hard‑wired panel applications. The compact, metal station is commonly used on small to mid‑range machines and conveyors where a dedicated open/close/stop control block is preferred in a single, install‑ready chassis, and it is designed to integrate with other 50 Series pushbutton components for scalable panel layouts.
