These units combine a current switch and relay into a single package, reducing the space required for total control of fans and pumps. The current switch and relay operate independently of one another. These devices allow start/stop control and status monitoring with one device instead of two. DETECTS BELT LOSS/COUPLING SHEAR!DETECTS BELT LOSS/COUPLING SHEAR! 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.
