The catalog number ATVAKDA20300WRU describes an
Automatic Transfer Switch with the switching devices
mounted vertically in the enclosure. The intelligence
represented by the control panel is microprocessor
based. The Cutler-Hammer Series C Type HKD is used
as the switching device and is in the form of a 2-pole
molded case switch on each source. The continuous
current rating of this equipment is 300 amperes and
applicable at 240VAC, 60Hz. The transfer switch equip-
ment is enclosed in a NEMA 3R enclosure and is listed
for UL/CSA applications.
