Motor disconnect switch

The Square D MD50 motor disconnect switch cuts power to a motor without affecting the main circuit. According to the company, IEC 60309-compliant technology makes it almost 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. Prewired for installation, the product also features a watertight ground hub, two grounding blocks, moveable mounting feet, and internal mounting tubes.

Control regimen

OptimalFlux is a control regimen for standard totally enclosed fan-cooled (TEFC) induction motors. According to the company, the regimen enables a standard TEFC motor to operate at a cooler temperature across its entire speed range. Available as an option with any of the company's standard CFW09 variable-frequency drives, it can also be used with the company's standard NHE or NPE motors rated from 1 hp to 300 hp.
