How is I-Line phasing designated in circuit breaker catalog numbers?

Product Line:
I-LINE Panelboards, Powerpact Breakers, Legacy Breakers

Below is a table in Digest 177, Section 9 on page 9-24 that illustrates the catalog numbering for ILINE breakers. Table 9.110 represents the number system for the Powerpact breakers. Table 9.111 represents the number system for the older Legacy breakers. Please note the absence of a phase option number after a 3-pole catalog number will result in an ABC phase connection.
