CSS Series
Solid Core Current Switches
The CSS models are ideal for new installations and provide the greatest savings
opportunity. Ideal for direct drive units, small
exhaust fans, and other fi xed loads, these
solid state switches have accurate, very low
fi xed or user adjustable setpoints. which
are activated when the desired amperage is
reached. The adjustable CSSGA2100NN and
CSSGA2100R1 units have LED’s which indicate switch status. (User can also adjust the
setpoint for over or under loads.)
Excitation is magnetically induced from current carrying conductor (wire or cable), making these units completely self-powered.
The CSS Series, solid core, current switch’s convenient wide orifi ce allows easy pass
through of the conductor, and is bundled with a mounting bracket and hardware, making
installation easy.
Model CSSGA2100R1 is equipped with a snap-on power relay for remote motor startup.

CSC Series
Split Core Current Switches
A signifi cant increase or decrease in operating current may result in motor, belt
loss, slippage, or mechanical failure, which
could jeopardize the user’s process. The
split core design of the Model CSC is an
ideal solution, as it can easily be clamped
onto existing power cables or wires.
These units are offered with industry standard 135 Amp or 200 Amp output and
very low fi xed or adjustable setpoints,.
which are activated when the desired amperage is reached. Model CSCGA2125NN
and CSCGA2125R1 include LEDs for indication of switch status. (Setpoint can be
adjusted for over or under loads.)
