Effective January 2019 Technical Data 10533 Supersedes September 2017 UL Recognized power distribution blocks Catalog number example: 16220-3 is a 3-pole 16220 Where: The prefix 16220 defines the blocks lineside characteristics (i.e., one conductor port per pole that accepts 2/0 - 14 Cu, or 2/0 - 8 Al conductors) and the loadside characteristics (i.e., four conductor ports per pole that each accepts 4 - 14 Cu or 4 - 8 Al conductors). The suffix 3 in this example defines this as a three-pole block. See the catalog number tables for details on the available lineside/loadside characteristics. How to order: From the catalog number tables, select the catalog number that defines the desired lineside/loadside port and conductor characteristics. Add to the catalog number the suffix that defines the desired pole configuration. Note, you must Catalog symbols: select from the available number of poles for each catalog number. These appear in the second 160 -(poles) column of the catalog number tables. 162 -(poles) 163 -(poles) Specifications: 164 -(poles) Ratings 165 -(poles) Volts: 600 V Amps: 175 to 1520 A Description: SCCR: up to 200 kA* (see table for SCCR by Bussmann series UL Recognized power catalog number) distribution blocks offer a variety of lineside and * Maximum SCCR contingent upon the application of an loadside port configurations to provide greater upstream current-limiting overcurrent protective device. flexibility in panel wiring and wire management.
