DESCRIPTION
The CSS models are ideal for new installations and provide 
the greatest savings opportunity. Ideal for direct drive 
units, small exhaust fans, and other xed loads, these sol-
id state switches have accurate, very low xed or user ad-
justable setpoints, which are activated when the desired 
amperage is reached. The adjustable CSSGA2100NN and 
CSSGA2100R1 units have LED’s, which indicate switch sta-
  
      
       
completely self-powered.
The CSS Series, solid core, current switch’s convenient 
wide orice allows easy pass through of the conductor, 
and is bundled with a mounting bracket and hardware, 
making installation easy.
