The GENERAL FILTERS GA51 is a 120V current sensing relay designed for blower control isolation. Ideal for electronic air cleaners and small load rated fans. It senses current rather than measuring voltage, making it more reliable and less expensive than traditional flow or pressure switches.
The GA51 current sensing relay is designed to be wired in series with a 120 volt load like a very small motor, electronic air cleaner or transformer.
