CURRENT STATUS SWITCHES
■ Adjustable mounting bracket...easy placement
The H708/908 solid and split core adjustable current
sensors provide accurate, reliable and maintenance free
fan and pump status indication.

■ Detect belt loss and motor failure...ideal for fan and

Loss of belt/coupling shear
■ Replace pressure switches and other electromechanical devices
Now you can easily detect drive belts slipping, breaking, or pump
coupling shear. In fact, a typical HVAC motor that loses its load
has a reduction of current draw of up to 50%. That's why our sensors
are the industry standard for status. It's proven and it really works!
■ Verify lighting circuit loads
■ Monitor critical motors (compressor, fuel, etc.)
■ Industrial process equipment status (OEM)

CURRENT STATUS SWITCHES
■ Monitor positive fan or pump status by sensing changes in current
flow resulting from motor failure, belt loss or slippage, and other
mechanical failures.Wiring runs are shorter than with differential pressure
switches, since the Hawkeye does not have to be located at the fan or pump
being monitored.
■ H708 (solid core) is ideal for new construction projects.
■ H908 (split-core) is ideal for retrofit projects.
