Rail mounted SW / DSW terminal blocks | Leading source of dependable electrical components | Curtis Industries Electrical Components for Industry

Series SW & DSW

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 (over for DIN modules) and with very little pressure snap into place. To remove, push center section of spring toward molding. Module will "pop free."

"D" Series made to mount on DIN track

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 50 amps/600 volts.

Durable Modular Construction - All SW and DSW 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.

Suffixes are used as follows:
2P 3P	Denotes 2-pole module Denotes 3-pole module

Example: a two-pole SWT module becomes stock number 2PSWT; a three-pole module becomes 3PSWT. Atwo-pole DSWT module becomes stock number 2PDSWT; a three-pole module becomes 3PDSWT.

For higher current blocks which may be combined with the SW and DSW series, see our W/DW Series.
