UL Listed power distribution blocks

Transcription

1 Technical ata ffective September 2017 Supersedes ugust 2016 atalog number example: P323-3 is a 3-pole P323 Where: The prefix P323 defines the block s lineside characteristics (i.e., one conductor port per pole that accepts 350 kcmil - #6 u/ l conductors) and the loadside characteristics (i.e., six (6) conductor ports per pole that each accepts #4 - #14 u or #4 - #12 l conductors). The suffix 3 in this example defines this as a three-pole block. See the catalog number table for details on the available lineside/loadside characteristics. atalog symbol: P (poles) escription: aton s ussmann series high Short-ircuit urrent Rating (SR) power distribution blocks provide up to 200 k SR and help achieve compliance with National lectrical ode (N ) and OSH requirements by resolving a common SR weak link in industrial control panels. vailable in 1-, 2- and 3-pole panel mount versions with popular lineside and loadside port configurations, these blocks are UL Listed and provide the requisite spacing between uninsulated opposite polarities or ground by meeting the UL through air and 2 over surface spacings required per UL 508 for feeder circuit applications and per N for field installations. To increase application flexibility, these blocks feature dual-wire rated ports that accept copper or aluminum conductors while retaining a UL Listed status. Optional covers are available to enhance electrical safety. How to order: rom the catalog number table, select the catalog number that defines the desired lineside/loadside port and conductor characteristics. dd to the catalog number the suffix that defines the desired pole configuration. Note, you must select from the available number of poles for each catalog number. These appear in the second column of the catalog number tables.

3 Technical ata ffective ugust 2016 eatures and benefits High SRs up to 200 k, assist in achieving high SR for a control panel per N and UL 508 requirements. In compliance with UL 1953 minimum spacing requirements for industrial control panel feeder and branch circuits. Optional covers available to reduce the risk of accidental contact with energized components. ual wire port application Rated for dual wire port application to increase the possible number of lineside and loadside connections..g., P220 can accept two wires into the lineside port (#4 - #14 u, #4 - #8 l) and two wires per port (eight connections per pole total) on the loadside lug (#8 - #14 u, #8 l). ual wire applications are only viable when using two wires of the same size, stranding, and insulating and conductor material in the same port. errule terminal application ussmann series P power distribution blocks are rated for use with UL Listed ferrules (see catalog number table for details). errule applications allow for the use of a broader range of conductor stranding and simulate a more efficient, solid wire connection with the P terminal port. lways use UL Listed ferrules in accordance with the manufacturer s specifications and instructions. Selecting SR power distribution blocks and terminal blocks Short-circuit current rated power distribution blocks ussmann series power distribution blocks have three distinct styles to match different application needs. There are the PS_ and P_ high short-circuit current rated power distribution blocks and the 16_ power terminal blocks. The differences are whether the power distribution blocks are enclosed or not, and whether they are UL 1953 Listed power distribution blocks or UL 1059 Recognized power terminal blocks, which have different minimum spacing requirements. The table on this page will assist you in selecting which block is right for your application. Why these are important Per the N and OSH, equipment cannot be installed in an electrical system at a location where the available fault (short-circuit) current is greater than the equipment s SR. urther, equipment SRs are required in the 2014 N and for UL 508 Listed control panels. Marking the equipment SR on control panels (N ), industrial machinery electrical panels Selection table This table provides an overview of the three ussmann series power distribution and terminal blocks mentioned above. or details on the PS blocks, see data sheet number or the 16_ blocks, see data sheet numbers (UL Recognized power distribution blocks), (splicer blocks) and (stud blocks). atalog symbol UL status nclosed High SR* PS_ P_ 16_ UL 1953 Listed power distribution blocks UL 1953 Listed power distribution blocks UL 1059 Recognized terminal blocks Spacing ** 1 air, 2 surface UL 508 panel branch circuit UL 508 panel feeder circuit HV UL 1995 Yes*** Yes Yes Yes Yes Yes Yes No Yes Yes Yes Yes Yes * When protected by proper fuse class with maximum ampere rating specified or smaller. ** or details, see P and T minimum spacing requirements for equipment table below. *** IP20 finger-safe under specific conditions, see data sheet no , page 5.

(N 670.3()), and HV equipment (N 440.4()) is required by the N. Power distribution and terminal blocks not marked with a component SR are typically one of the weakest links in a control panel s equipment SR and may limit the equipment SR to no more than 10 k. The PS_ and P_ products have the increased spacing required for use in feeder circuits of equipment listed to UL 508 (UL 1059 terminal blocks must be evaluated for proper spacings). lso, for building wiring systems, the PS_ and P_ power distribution blocks can be used to meet the 2014 N requirements in section () for power distribution blocks in wireways.
