MENNEKES NEMA 4X Stainless Steel Motor Disconnects are a series of 3 pole 600V Switches with a maximum rating of 50hp. Ideally suited for installation on branch motor circuits as a load rated lock-out device, units are “Suitable as Motor Disconnect” per NEC Article 430 Requirements.

Available in three enclosure sizes, all units have a 180° Swing Door cover for convenient access to the interior. Pour-in-place gasket, stainless hardware and compact size allow for use in numerous applications where water and corrosion are present. MENNEKES ST series switches are a rugged and economical alternative to large blade style stainless switches.
