SQUARE D INTRODUCES VENTILATED NEMA TYPE 3R
MCC
FOR ENCLOSING AC DRIVES, SOFT STARTS
Enclosures lower maintenance and installation
costs, help increase uptime
PALATINE, Ill. - Aug. XX, 2002 - Traditionally, motor control
center (MCC) drive and soft start outdoor packages (NEMA 3R
enclosures) were designed as special engineered solutions that
included air conditioners or other expensive cooling packages
and required installation under a permanent shelter. To solve
this problem, Square D/Schneider Electric has introduced a standard
ventilated NEMA Type 3R MCC for enclosing SQUARE D® AC drives
and soft starts. The SQUARE D Model 6 MCC will increase uptime
and reduce costs without sacrificing performance.
This new MCC may be applied wherever motors are located outdoors
and can benefit from speed control or soft starting. Typical
applications include water/wastewater pumping stations, petrochemical
pump control, pipeline and oilfield drilling, asphalt/aggregate
plant control, commercial construction HVAC controls, utility
pump control and OEM/system integrators.
The fan-forced ventilated design, with louvered and filtered
openings and various self-contained environmental controls,
prevents drives and soft starts from shutting down due to overheating.
Cooling is achieved with fans, eliminating expensive cooling
options, such as air conditioning. The filtered louvers located
in the MCC door help keep debris out of the MCC.
The air pressure inside the cabinet, produced by the positive
pressure ventilation system, helps force out dirt and contaminants.
This provides a cleaner environment for the drive and soft start
electronics than would be created with exhaust fans mounted
at the upper vents.
The dual door fans, which have been weatherized for outdoor
use, circulate fresh air through the enclosures, prolonging
the life of the MCC and reducing maintenance costs. Space heaters
and humidity controls supply heat when necessary to prevent
condensation from forming, thus preventing unwanted shutdown
of the drives and softstarts. On account of the self-contained
power supply, there is no need for external power from the customer.
