July 23, 2008—The new UL 508-listed Square D brand MD50 motor disconnect switch from Schneider Electric provides reliable, safe and quick power connections in industrial facilities, and prevents process interruption by cutting power to a motor if necessary while not affecting the main circuit, says the company.
IEC 60309-compliant technology helps the Square D brand MD50 increase safety on a plant floor by making it virtually impossible to plug in a power receptacle having different voltage and ampere ratings, while a mechanical interlock forces an 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 brand MD50 is appropriate for applications like food processing, packaging, automotive assembly, material handling/conveyance, textiles, mining, petrochemical refining and pulp/paper manufacturing.
The Square D brand MD50 is a pin-and-sleeve interlocked switch receptacle listed UL 508 “Suitable For Use as a Motor Disconnect,” meaning it provides a disconnect means for motors as permitted by National Electrical Code (NEC) 430.109(6).
A watertight ground hub and two grounding blocks provide both equipment and metallic system grounds for the Square D brand MD50. In addition to pre-wiring, it features moveable mounting feet for irregular surfaces, and internal mounting tubes help when mounting space is limited.
