Carrier NSA-A/CS2 Installation Instructions Manual

#NSA-A/CS2, NSA-A/SCS2, NSA-A/SCS2-L – 11/14/2019
Overview
The Carrier Fixed "Status" Current switches are designed for use in any AC current
monitoring application in which you are looking for a "Go/No Go" or On/Off status for a
particular piece of equipment. The current switches should be installed on the line side
of the power to the motor, pump, compressor or other equipment. The current switches
are available in both solid and split-core versions which also includes a Patented 35 mm
Din Rail mounting foot for easy installation in panel mount applications. The solid-core
versions are a great choice for new installations or OEM applications in which cost
sensitivity, lower trip points and environmental issues may be of concern. The split-core
version of the current switches work great in retrofit applications and for use in service
vehicles since one part will work in most applications and can be installed without
disconnecting any wires. The fixed current status switches can also be used to
determine the run time of your equipment and basic load trending applications where you want to know when your piece of
equipment runs and for how long it runs for when logging the contact closures on your building management system or
PLC.
Applications: Pump Status, Fan Status, Compressors, Motor Status, Ovens, Industrial Equipment, Lighting Status and
Usage, Electrical Load Status, Local Alarms (Strobes and Audible Alarms)
NOTE The Fixed Current Switches are not intended to be used in Life / Safety applications or in Hazardous / Classified
locations.
