Series SW & DSW
.375" (9 .52mm) Center-to-Center Spacing
Features:
•
Snap-In Track-Type Concept
– To assemble two or three-
pole 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 nylon
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
–3/8" center-to-center terminals provide
compact circuit density . 32 poles per foot – 192 per six foot
length .
•
Terminal Flexibility
– Three different terminal variations are
available . Ratings up to 50A/600V .
50A/600V
•
Durable Modular Construction
– All SW models feature
moldings of break-resistant nylon .
•
May be pre-assembled on track
•

How to Order
SW and DSW Series modules are ordered by listing a
composite number made up of the model designation
preceded by the number of poles per module .
Prefixes are used as follows:
2P denotes 2-pole module
3P denotes 3-pole module
Example: a 2-pole SWT module becomes stock number
2PSWT; a 3-pole module becomes 3PSWT .
