Description
Schneider Electric LRD4365 TeSys LRD Thermal Overload Relay is a protective device used in electrical circuits to protect motors from damage caused by overheating. Monitors the current flowing through the motor and trips when an overload condition is detected.
80-104A is the current range for which the relay is designed. It can handle motor currents between 80 and 104 amps. Class 10A is the trip class of the relay. The trip class determines the time the relay needs to trip in the event of an overload. The relay trips within 10 seconds when the motor current exceeds the specified range.
Features
- 80-104 Th Overload Relay
- Protect motors against overloads and phase failure.
- Connection by screw clamp terminals.
