Three motor-protection relay units allow users to select the range of protection that best fits their application requirements. The basic unit, the F3I, guards against current surge, phase loss, and phase unbalance. The F31T offers protection against overheating, and the FWIT covers overheating and phase-reversal protection. Technical user guide includes information on operating principles including current surge, asymmetry and phase fault, overtemperature, and phase order. Product specifications are listed and a chart is included on protection functions.
