ATC-300/900 Breaker Based Transfer Switch
1.3 ATS Catalog Number Identification
Transfer switch equipment catalog numbers provide a significant
amount of relevant information that pertains to a particular piece
of equipment. The Catalog Number Identification Table (Table 2)
provides the required interpretation information. An example is
offered here to initially simplify the process.

The catalog number ATV3KDA20225WRU describes an ATS with
the switching devices mounted vertically in the enclosure. The
intelligence represented by the control panel is the ATC-300+.
The Eaton 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 225 A and applica-
ble at 240 Vac, 60 Hz. The transfer switch equipment is enclosed
in a NEMA 3R enclosure and is listed for UL applications.

Notes:
1 Vertical orientation (225-1200 A)
2 Horizontal orientation (30-150 A)
3 Consult factory for availability.

CSA will only be applied to molded case switches, both
power sources.
1.4 Environmental Conditions
1.4.1 Seismic
With proper installation, and by including the appropriate optional
feature that includes specially designed cleats (optional feature
#42), the ATSs have a seismic capability which exceeds the worst
case Zone 4 required levels, per both the Uniform Building Code
and the California Building Code.
1.4.2 Operational Conditions
Normally, an ATS is applied indoors in an electrical equipment
room. In the appropriate enclosure, it can be used for outdoor
applications were the equipment is subject to falling rain, freezing
temperatures, and no greater than 90% humidity (non-condens-
ing). The ambient temperature range for operation is between -20
and 70°C (-4 to 158°F).
