PreSet™

Adjustable Current Switches

Scaled calibration for proof of flow set-point
Split and solid core models to 150A
N.O. 30VAC/DC or 120VAC output
Optional command relay

Patent Pending
Energy Monitor
E474343
DESCRIPTION APPLICATIONS
PreSet™ allows for matching sensor set-point to the motor nameplate, ▪ Detecting belt loss, coupling shear, and
eliminating the need to calibrate in energized enclosures and reducing mechanical failure on fans and pumps
installation time. Sensor will detect motor undercurrent conditions such as ▪ Monitoring status of industrial processes
belt loss, coupling shear, and mechanical failure on fans and pumps. ▪ Monitoring status of critical motors

FEATURES

Save time and money while eliminating
calibration inside energized enclosures

▪ Preset™ scaled calibration enables set-point adjustment
for proof of flow by simply matching dial to motor full load
amps (FLA) nameplate
▪ Safer: Eliminates calibration in energized enclosures, Simply set to motor FLA
reduces arc flash hazard for proof of flow set-point
▪ No need to return to calibrate—saves time and money
▪ Super low turn-on Patent Pending
Maintenance-free—no call backs

▪ Superior to traditional adjustable CTs and pressure switches
▪ Industry leading 7 year warranty

No hazardous guesswork. Multi-turn
adjustments are a thing of the past.
