Abstract
The motor relay includes thermal models representing the start and run conditions of a motor. The thermal models are implemented using measured current values and certain known operating parameters available from the manufacturer, specifically full load current, locked rotor thermal time and rated service factor. The thermal model information is compared with threshold thermal model values to determine when an overload condition has been reached.
