Description
Schneider Electric LRD365 TeSys LRD Thermal Overload Relay is a protective device used in electrical circuits to protect motors from overloading. It works by monitoring the current passing through the motor and tripping if it exceeds a certain threshold for an extended period. 48-65A indicates the current range that this particular thermal overload relay is designed to handle. It means it is suitable for motors with a current draw between 48 and 65 amperes.
Class 10A is the tripping time of the relay. The relay is designed to trip when the current exceeds a threshold for a relatively short period. The exact tripping time might vary slightly based on the specific model and manufacturer, but generally, in Class 10A, the relay trips within 10 seconds when the current exceeds the specified limit.
So, in summary, Schneider Electric LRD365 TeSys LRD Thermal Overload Relay is designed to protect motors with a current draw between 48 and 65 amperes. It's set to trip relatively quickly if the current exceeds the specified limit, which is important for protecting the motor from damage due to overheating.
