SW140

NO - SP - ST - 1U

The SW140 has been specifically designed to be installed within the confines of a Power Distribution System 1U rack.  This compact busbar mounted contactor follows the recognised design of the SW150 series of contactors and is devised for uninterrupted loads.  They are primarily for use with direct current loads but can be used for alternating current loads.

The SW140 features single pole double breaking main contacts with silver alloy tips which are weld resistant, hard wearing and have excellent conductivity.  Silver plating on the main contacts is standard for the SW140, however optionally it can be excluded from the specification.  Mounting can either be horizontal or vertical, but if mounted vertically, the coil should be at the bottom.  If the coil is required at the top, we can adjust the contactor to compensate for this.  The SW140 is easy to install, with “L” Shape Mounting bracket kits fitted as a standard option, or alternatively the M4 tapped holes in the switch frame can be used.  To suit the limitations of space of a 1U rack, the coil connections are supplied as flying leads.
