1–4 Trip Unit Catalog Numbers

A simple catalog-numbering system defines all of the

standard and optional Trip Unit functions. A catalog

numbering key is found inside the front cover (but see

Table 1 for the complete list of supported breakers). Each

of the segments of the catalog number is described below.
The first five-character group indicates the breaker type

for which the Trip Unit is configured, as listed in Table 1.
