Series W 7/16" (11.11mm) Center-to-Center Spacing Series W Variations and Terminal Designations WT Solderless electro-tinned tubular connector with No. 10-32 terminal screws. Accepts wire from No. 16AWG to No. 8AWG. Rated 50A/600V. WTC Solderless electro-tinned tubular connector with No. 10-32 terminal screws capitivated by traveling pressure pad. Accepts wire from No. 22AWG to No. 8AWG. Rated 50A/600V BARRIER STYLE High Voltage/Current Features: ‡ Snap-In Track-Type Concept – To assemble two or threepole modules simultaneously, simply insert one edge of the module under the flange of the track and with very little pressure snap into place. To remove, push center section of spring toward molding. Module will “pop free.” ‡ Total Modular Principle – Two and three-pole phenolic modules are complete with white fiber marking strips and retaining springs. ‡ Reduced Inventory – No end moldings, mounting brackets or metal mounting clamps are needed for assembly. ‡ Compact Design –7/16" center-to-center terminals provide compact circuit density. 164 poles per six foot length. ‡ Terminal Flexibility – Three different terminal variations are available. Ratings up to 75A/600V. ‡ Durable Modular Construction – All W models feature rugged thermo-set phenolic moldings. ‡ May be pre-assembled on track ‡ Wire Sizes – Types WT with No. 10-32 tubular terminal screws UL recognized for No. 16AWG to No 8AWG. Type WTC tubular clamp terminal with No. 10-32 screws UL recognized for No. 22AWG to No. 8AWG. Type WH with 5/16-24 terminal screws UL recognized for No. 22AWG to No. 4AWG. ‡ Recognition and Listing – UL recognized and CSA certified Recognized under the Components Program of Underwriters Laboratories, Inc.

Prefixes are used as follows: P denotes 1-pole module 2P denotes 2-pole module Example: a 2-pole WT module becomes stock number 2PWT and a WH Type available as single terminal module only is referred to as PWH. .437 .218 Dia.

To order, specify: Part No. 271A11 (2PW) Part No. 271A13 (3PW) 100-ft. Rolls – Part No. 20W Pins – Part No. 21W When ordering non-DIN track to a specified size, simply designate model followed by length required, expressed in poles. Example: SW with space for 24 poles plus two mounting holes becomes stock number SW-24. For standard three and six foot lengths, simply designate model followed by 96 or 192 respectively (SW Series) or 82/164 (W Series). Examples: SW-96 or SW-192; W-82 or W-164. For DIN track, specify DT and length of track desired (in 2.5 centimeter increments). For example, DT-10 designates DIN track 10 centimeters in length. Dimensions are ± .10 cm. Fuse blocks, knife switches and WH Type terminal assembles are the same width as two-pole W modules and therefore require twice the space of a single pole W. TERMINAL JUMPER CONNECTS BARRIER STYLE Series W Accessories ‡ STURD< TRAC. – constructed of heavy steel with zincdichromate plating. Mounting holes are 7/32 inch diameter and provided continuously on 3/8 inch center-to-center spacing (SW Series) and 7/16 inch centers (W Series). DIN mounting holes are slots .248" wide by .709" long on .984" center-to-center spacing. ‡ EC2N2MICAL STANDARD LENGTHS – mounting track available in three and six-foot pre-cut lengths for self-cutting to application needs. DIN track available in two meter (78.74") lengths. ‡ PRE-CUT TRAC. – available for large volume work where identical lengths are used. Save cutting time in your plant. ‡ SW, DSW, W AND DW SERIES C2MPATI%ILIT< – track accommodates both W and SW Series of snap-in track type modules with any combination of terminal assemblies, fuse blocks, etc. DIN track accommodates DW and DSW Series modules.
