Table 1.2 Transfer Switch Catalog Number Explanation
The switching devices have a high withstand
rating (Table 1.1). The high-speed, stored-energy switch-
ing mechanism guarantees a transfer time of
less than 5 cycles.
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. An example is offered to ini-
tially simplify the process.
Example: Catalog number (circled numbers correspond
to position headings in Table 1.2):
The catalog number CTVISPA31000XSU describes a
closed transition automatic transfer switch with the
switching devices mounted vertically in the enclosure.
The intelligence represented by the IQ Transfer 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.
