Safe to be Square

The new Schneider Electric Square D brand MD50 motor disconnect receptacle switch provides reliable, safe and quick power connections for motors, the company says. IEC 60309-compliant technology helps the Square D brand MD50 increase plant floor safety by making it virtually impossible to plug in a power receptacle having different voltage and ampere ratings. A mechanical interlock requires the operator to insert a plug before power can be turned on, and to turn power off before the plug can be removed. Pre-wired for quick and easy installation, the Square D MD50 is appropriate for applications like food processing, packaging, automotive assembly, material handling/conveyance, textiles, mining, petrochemical refining and pulp/paper manufacturing, Schneider says. The IEC-compliant platform of the Square D MD50 provides a quick and easy method for companies to standardize their electrical component specifications worldwide, because it is compatible with any manufacturer’s product conforming to the IEC 60309 standard and colour coding. A watertight ground hub and two grounding blocks provide both equipment and metallic system grounds for the Square D MD50. In addition to pre-wiring, it features moveable mounting feet for irregular surfaces, and internal mounting tubes help when mounting space is limited.
