Transfer Switch 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 16-55) provides the required
interpretation information. An example
for an open transition switch is offered
to initially simplify the process.
Example: Catalog Number (circled
numbers correspond to position
headings in Table 16-55).
The catalog number CTVCMGE32000XRU
describes a Soft Load ATS with the
drawout switching devices mounted
vertically in the enclosure. The intelli-
gence, represented by the ATC-5000, is
a microprocessor-based logic package.
The Magnum Breaker is used as the
switching device and is a 3-pole
molded case breaker for each source.
The continuous current rating of this
equipment is 2000 A and is applicable
at 480/277 Vac, 60 Hz. The transfer
switch equipment is enclosed in a
NEMA 3R enclosure and is listed for
Underwriters Laboratories (UL).
Catalog Numbering System

Using the Catalog Numbering System provides an overview of the ten basic style/feature categories
which generate the 15 digit catalog number.
