Description
Schneider Electric LRD4369 TeSys LRD Thermal Overload Relay is a protective device used in electrical circuits to prevent motors or other components from overheating. 110-140A is the current range the relay is designed for. This means it is suitable for motors or loads with a current draw between 110 and 140 amps. The term Class 10A refers to the trip class of the thermal overload relay. Trip classes define the time required for the relay to trip at a specific overload current. Class 10A means that the relay will trip within 10 seconds when exposed to a current six times the rated current.
Schneider Electric LRD4369 TeSys LRD Thermal Overload Relay is used in applications where the motor or device to be protected has a normal operating current within the specified range and a relatively quick response to overloads is desired.
