DESCRIPTION

The CSS solid core and the CSP split core current switches 

have either Normally-Open (N.O.) or Normally-Closed (N.C.) 

output configurations. All of these sensors will have a solid-

state output with an adjustable trip point (setpoint). These 

current switches are ideal for providing status information on 

any type of AC current using equipment. The CSS series 

current switches are an excellent choice for new installations. 

The CSP series current switches are ideal for retrofit or 

existing installations since it is not necessary to power down 

the unit and disconnect any wires during the installation 

process. The CSS and CSP current switches are accurate, 

reliable, easy to install and require less servicing than 

differential pressure switches, flow switches and paddle 

wheels.

These current switches should be used in applications in 

which a current switch with adjustable trip point is required. A 

current switch can be used to monitor fan and pump status, 

motors, compressors and electrical equipment for proper 

operation. A change in the operating current may indicate 

motor failure, belt loss/slippage or mechanical failure. Any 

time one of these events occur the current can significantly 

increase or decrease, thus tripping the sensor and notifying 

building management of an alarm condition.

The CSS and CSP series current switches can be used to 

monitor devices with a maximum continuous operating current 

of up to 200 or 250 Amps depending on the model. These 

switches will not need to be externally powered since the 

power for the switch is induced from the conductor being 

monitored. Another great feature of the CSS and CSP series 

current switches is that they include both a red and green LED 

that will indicate the “Status” of the switch contacts. All of 

these units come with a unique 1-3/8 in. (35 mm) DIN rail 

mounting flange and a limited five year warranty.
