The LRD4365 thermal overload relay from Schneider Electric's TeSys series is crafted to safeguard motors by preventing overheating. It supports a thermal adjustment range between 80 and 104 amperes, which allows for tailored settings based on the specific needs of the application. This particular model is classified under Class 10A for trip ratings.

Constructed with three poles, the relay provides effective control and monitoring functions. It includes one normally open (N.O.) auxiliary contact and one normally closed (N.C.) auxiliary contact, facilitating integration into various control operations. The relay operates effectively within a temperature spectrum from -20 °C to 60 °C. It is engineered to withstand temperatures as low as -60 °C during storage and can tolerate heat up to 70 °C. Its environmental specifications permit relative humidity levels ranging from 5 to 95%, provided that condensation does not occur.

Designed with an IP20 rating, the LRD4365 offers some protection against dust and contact with large objects, yet it is meant for indoor applications where additional protective measures may be necessary. The LRD4365 thermal overload relay is an essential component for ensuring the safe operation of electric motors in industrial settings.
