Thermal overload relay TeSys LRD 5.5-8A screw terminals LRD12

Overload relay – reliable motor protection

The TeSys LRD12 overload relay from Schneider Electric is a key element in protecting electrical circuits and motors. Designed to work with TeSys Deca series contactors, it provides effective protection against overload, phase failure and other motor malfunctions. With a current setting range of 5.5…8A, it is ideal for use in a variety of industrial and commercial installations.

#### Functionality and application

The LRD12 relay protects AC circuits and motors from the effects of overload, which can lead to damage and downtime. Its construction based on the principle of bimetallic temperature compensation guarantees precise operation over a wide range of ambient temperatures (-20…60°C). The ability to choose the reset mode – manual or automatic – allows you to adapt the relay's operation to the specific needs of the application. A built-in test button allows you to check the correct operation of the relay at any time.

#### Construction and mounting

The LRD12 relay is characterized by simple direct mounting, which facilitates its integration with existing installations. It has screw terminals for wire connections, ensuring secure and reliable electrical connections. Compact dimensions (45 mm wide and 70 mm deep) allow the relay to be installed even in limited space. It has one normally open and one normally closed auxiliary contact, allowing remote monitoring of the relay status and integration with control systems.
