1.3 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 1.2) provides the required
interpretation information for both closed and open tran-
sition switches. An example for an open transition
switch is offered initially to simplify the process.

ed vertically in the enclosure. The intelligence repre-
sented by the ATC-600 is a microprocessor-based logic
package. The System Power Breaker (SPB) is used as
the switching device and is a 3-pole insulated case
switch for each source. The continuous current rating of
this equipment is 1000 amperes and applicable at 480
VAC, 60Hz. The transfer switch equipment is enclosed
in a NEMA 1 enclosure and is UL listed.
