The TNF Series is based on the TF Series but is designed for frequent repetitive tripping action. It has a low internal hysteresis loss for precise tripping torque. 
Capable of Repetitive Operation
For frequent torque activation
High Accuracy
Excellent trip torque accuracy
Easy to Adjust
Trip torque can be adjusted by simply turning the adjustment nut.
No Play
Zero backlash
Various Mounting Options
Directly mounts to dials, gears, sprockets, arms, and other output masses.
Longevity
Low internal hysteresis loss minimizes age deteriotation.
