   The 8347 and 8348 supplementary overloads are automatic, disc-type, quick-trip devices that sense and operate on locked rotor current. They respond to motor current only. These controls were developed to supplement Klixon motor winding thermostats in protection systems for hermetically-sealed compressors from 2 to 12 horsepower and three-phase motors. Motor winding thermostats used alone often do not provide adequate protection on locked rotors since termperature responsive devices may not react quickly enough.
Warning
