Solid Core and Split Core Adjustable
Current "Status" Switches
CSS-O, CSS-C; CSP-O, CSP-C
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.
FEATURES
• Very low operating trip points
• LED status indication
• Integral DIN rail mounting flange
• Easy wiring, non-polarity sensitive
• Accepts up to a 350 MCM (17.3 mm) cable
• Operates up to 200 or 250 continuous amps
• RoHS and WEEE compliant
• Limited five year warranty
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.
