Siemens Thermal Overload Relays are electrical protection devices used to protect motors from damage due to excessive current. They are designed to trip and disconnect the power supply to the motor if the current exceeds a pre-determined level for a specified time period.
Thermal Overload Relays work by monitoring the temperature of the motor windings, and if the temperature exceeds a certain limit, the relay trips and disconnects the power supply to the motor. This protects the motor from damage due to overheating caused by excessive current.
