Description
Schneider Electric LRD32 TeSys LRD Thermal Overload Relay is a protective device used in electrical circuits to prevent motors or other equipment from overheating and getting damaged due to an overload condition. The 23-32A is the range of current. Class 10A is the tripping time characteristic of the thermal overload relay.
In this case, Class 10A means that the relay will trip if the current exceeds the specified range by a factor of 10 in a relatively short period of time. This is typically used for applications where rapid tripping is required to protect sensitive equipment or where short-term overloads are expected.
In summary, Schneider Electric LRD32 TeSys LRD Thermal Overload Relay is designed to protect electrical circuits with a current range between 23 and 32 amperes.
