Abstract
Induction motors require thermal protection to prevent overheating to cyclic as well as steady state overloads. This paper discusses the problem that occurred while a customer was testing the motor relay that trip prematurely when subjected to cyclic loads that do not overheat the motor and the characteristic curves are analyzed.
