Provide quick power connections and prevent process interruption—while not affecting the main circuit—with the UL 508-listed Square D brand MD50 motor disconnect switch from Schneider Electric. The IEC 60309-compliant technology helps the disconnect switch increase safety on a plant floor by making it virtually impossible to plug in a power receptacle with different voltage and ampere ratings. The switches are available in 20, 30, 60, and 100 amp units that feature a NEMA4X enclosure, designed for corrosive or washdown environments.
