Based on their operating principles, overload protectors can be categorized into mechanical and electrical types; mechanical versions primarily include torque limiters, torque-holding devices, and linear force limiters, while electrical versions mainly consist of motor overload protectors.
Overload protectors are widely used for the protection and monitoring of industrial three-phase motors and other electrical equipment across sectors such as machinery, metallurgy, construction materials, chemicals, and textiles.
Their applications have expanded to include power generation, mining, printing, packaging, extrusion, and material handling, as well as fields such as industrial robot joints, automotive transmission systems, wind turbines, machine tools, conveyor belt drive systems, aerospace actuators, marine propulsion systems, construction machinery, packaging machinery, and medical equipment.
