Current pressure switches
April 17, 2008 by Manufacturing AUTOMATION
Setra Systems’ new CSS Series and CSC Series of current pressure switches use magnetic current sensing technology and are recommended for HVAC/R, industrial, and lighting applications that use electric motors to drive fans, pumps, and blowers, and for sensing the status of heating coils and lighting. These solid-state switches are offered with industry standard 135 Amp or 200 Amp output and very low, fixed or user-adjustable setpoints, which are activated when the fault current is reached. The CSS series features three models, which are available with setpoints as low as 0.25 Amps. The CSC series features five models, which are available with setpoints as low as 0.15 Amps. The adjustable setpoint models can be adjusted to signal either loss of load or overload conditions. Switch load capacity is 1 Amp @ 30 V AC/DC maximum. In addition, the CSS and CSC series feature models equipped with switch LED indicators for switch status, as well as models with a snap-on-power relay and LED indicators for remote motor stop or start.
