Thermal overload relay TeSys LRD 2.5-4A screw terminals LRD08

Thermal overload relay TeSys LRD 2.5-4A is a reliable device used to protect electric motors and circuits from the effects of overloads. Designed by Schneider Electric, model LRD08 offers effective protection against overload, phase failure, prolonged starting, and rotor blocking. It is a key element in ensuring the safe and efficient operation of electrical installations.

Functionality and application

This relay is compatible with TeSys Deca series contactors, making integration into existing automation systems easier. Its current setting range (2.5…4 A) allows for precise adjustment to the characteristics of the protected circuit. Designed for direct mounting, it provides convenient installation and minimizes the need for additional mounting elements. It has a built-in reset button for manual reset after activation, as well as an automatic reset function for continuous operation without operator intervention.

Advantages for the installer and user

• Versatility: Compatibility with a wide range of TeSys Deca contactors simplifies selection and integration in various industrial applications.
• Precision: A current setting range of 2.5-4A allows for accurate matching to the load, minimizing the risk of unnecessary shutdowns or insufficient protection.
• Safety: A tripping class of 10A provides effective protection against overloads and short circuits, protecting motors and electrical installations from damage.
• Convenient installation: Direct mounting simplifies installation and reduces costs associated with wiring.
• Status indication: It has built-in auxiliary contacts (1 normally open, 1 normally closed) allowing for signaling of the trigger status and remote monitoring of the device's operation.
• Durability: Made of high-quality materials, it ensures long-lasting and reliable operation even in harsh industrial conditions.
• Temperature compensation: Ensures stable operation in varying ambient temperatures, maintaining protection accuracy regardless of external conditions.
• Phase failure protection: Protects motors from damage caused by the absence of one of the supply phases.

The LRD08 relay is a solid solution for professionals looking for reliable motor protection and for end-users who value the safety and long-term operation of their equipment. The use of screw connections guarantees secure and durable electrical connections, and the ability to seal the settings protects against unauthorized changes to the device's operating parameters.
