Description
The TeSys LRD thermal overload relay is designed for protection of motors from overheating caused by excessive current. It is part of the TeSys series from Schneider Electric. Here are the key specifications for the model you’re referring to:
- Current range: 9…13 A.
- Thermal protection class: Class 10A, which means the relay will trip the circuit after 10 seconds to 1 minute of overload conditions depending on the level of overload.
- Function: The LRD provides thermal overload protection, adjusting to the motor’s characteristics and preventing damage due to excessive current or overheating.
- Adjustability: It offers an adjustable setting within the specified range, allowing you to set the precise protection according to the motor’s specifications.
- Applications: This relay is commonly used in industrial and commercial settings to protect motors from overloading, ensuring operational safety.
