Description
Schneider Electric LRD4367 TeSys LRD Thermal Overload Relay is a protective device used in electrical systems to protect motors from damage caused by overload or excessive current. The relay is suitable for circuits with a current rating between 95 amps and 120 amps.
Class 10A means that the relay is designed to trip within a certain period of time when the current exceeds a certain threshold. Class 10 means the relay will trip and disconnect the circuit if the current reaches 600% of its nominal value within 10 seconds. The letter A indicates that it is an inverse delay characteristic, meaning that the trip time shortens as the current increases.
Overall, Schneider Electric LRD4367 TeSys LRD Thermal Overload Relay is designed for the protection of motors in circuits with a rated current between 95 and 120 amps. It is set to trip relatively quickly when the current exceeds 600% of its rating, and the trip time decreases as the current increases.
