CURRENT MONITORING
DETECT BELT LOSS, COUPLING SHEAR, AND
MECHANICAL FAILURE
5Year
Warranty
H308
Smallest in the industry (patent pending)
H608
Small split-core housing is great for retrofits
Current Switches: Adjustable
Trip Point, Standard Output
Hx08 Series and H701 current switches offer high
performance, with a wide array of amperage range
options. These products can accurately detect belt
loss, coupling shear, or other mechanical failure on
loads from 1/5 to 100HP.
High performance devices in split- and solid-core
housings
 Minimum trip point as low as 0.5A (H608)...
eliminates the need for multiple wraps of the
conductor through the sensor even on loads as
small as 1/5HP
APPLICATIONS
 Small size...fits easily inside small enclosures
 Detecting belt loss, coupling shear, and
 Self-gripping iris on the split-core housing for
mechanical failure
easy installation
 Verifying lighting circuit and other electrical
 Status LEDs for easy setup and local indication
service run times
(no LED on the H701)
 Monitoring status of industrial process equipment  Bracket on H908 can be installed in three
different configurations
 Monitoring status of critical motors (compressor,
fuel, etc.)
 1 Amp status output for increased application
flexibility
 All devices are 100% solid state and polarity
insensitive, with a 5-year warranty

Now you can easily detect when drive belts slip,
break, or pump couplings 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.
