Installation & Operation Instructions
PRECAUTIONS
• This product is not intended to be used for
Life or Safety applications.
• This product is not intended for use in any
hazardous or classified locations.
• The A/CTA2 and A/SCTA2 Series Current
Sensors must be used on Insulated
Conductors Only.
HIGH VOLTAGE
• Disconnect and lock out all power sources
before installation as severe injury or death
may result from electrical shock due to
contact with high voltage wires.
GENERAL INFORMATION
The 4-20 mA Output Analog Current Sensors are designed
for use in any AC current monitoring application in which
you are looking to monitor a particular piece of
equipment. Applications may include monitoring a
resistive type load such as an incandescent light bulb,
heating element as well as any single speed linear load.
For currents monitored above 250 Amps, the CTA2-5 and
SCTA2-5 are ideal for use with a step down Ratio:5A
Output CT (Current Transformer) in stepping down
current in a monitored conductor to a proportional 0 to 5A
output signal. The current sensors are available in both
solid and split-core versions which also includes a
Patented (Pat. No. US 7,416,421) 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 like dust and moisture
may be of concern. The split-core version of the current sensors work great in retro t applications and for use on service
technicians vehicles since one or two parts will work in most applications and can be easily installed without
disconnecting any wires.
INSTALLATION
Make sure that all installations are in compliance with all national and local electrical codes. Only quali ed
individuals that are familiar with codes, standards, and proper safety procedures for high-voltage
installations should attempt installation. The current sensor is a 2-wire, 4 to 20 mA Loop Powered device
