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
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 the
table below.
The catalog number
CTVCMGE32000XRU
describes a Soft Load ATS
with the drawout switching
devices mounted vertically
in the enclosure. The
intelligence, represented
by the ATC-5000, is a
microprocessor-based
logic package.
The Magnum breaker is used
as the switching device and
is a three-pole molded case
breaker for each source.
The continuous current rating
of this equipment is 2000A
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).
