The new Yaskawa NEMA enclosure carries a UL Type 3R label, and has been designed to provide a high degree of outdoor protection against rain, snow, and sleet, as well as defend against airborne dust particles as small as 10 microns in size. Standard features of the new enclosure include door locking (keyed door handle or padlock hasp), force ventilation, door mounted drive operator keypad, and dual current rating on data nameplate for 40° C and 50° C operating ambient temperature.
According to Tim Wallschlaeger, Yaskawa Electric America's Product Marketing Manager for the new enclosure, "The challenge was to develop a top quality standard enclosure that would be readily available through our distribution channels and still be flexible enough to be used in custom OEM designs and customer specific engineered orders. We believe we've achieved that objective - at a very reasonable price - and also added a significant list of optional design features."
Design features being offered as options on the new enclosure include:
o Floor mount kits for all sizes
o Lighting protection (Transient Voltage Surge Suppressor)
o Space heater and thermostat (operate at minimum -30° C, 100% humidity)
o Air-to-air heat exchangers for use in extremely dusty environments (NEC rated amps at 40° C Ambient.)
o Hinged viewing window for viewing keypad operator
While primarily designed to accommodate Yaskawa's E7 drive, according to the company the new enclosure can also be configured for Yaskawa's P7, F7 and G7 drives.
