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.
