Thermal overload relay TeSys LRD 4-6A screw terminals LRD10

Overload relay – reliable motor protection

The TeSys LRD10 thermal overload relay is a key element in protecting electrical installations and motors. Designed by Schneider Electric, the LRD10 model offers effective protection against overload, phase failure and other irregularities that can lead to motor damage. The device is compatible with TeSys Deca series contactors, ensuring easy integration and high functionality in control systems.

Functionality and application

The LRD10 relay is designed to protect alternating current circuits. Its current setting range of 4…6 A allows it to be adapted to various applications. Thanks to the Class 10A trip characteristic, it provides a quick and precise response to hazards. Built-in auxiliary contacts (1NO + 1NC) allow remote monitoring of the circuit status and signaling of failures. The automatic reset function simplifies system restart after the cause of the short circuit has been removed, and the reset button allows manual reset if necessary.

Construction and characteristic features

The TeSys LRD10 relay is distinguished by its solid construction and high quality workmanship. Direct mounting simplifies installation, and the screw connection of the main contacts ensures a reliable electrical connection. The device has a built-in test mechanism that allows you to check its correct operation. Additionally, the ability to protect settings against accidental changes using a transparent cover increases safety and reliability. Compact dimensions (66 mm x 45 mm x 70 mm) allow mounting in limited space. Operation at temperatures from -20°C to 60°C guarantees reliability in harsh industrial conditions.
