Thermal overload relay TeSys LRD 16-24A class 10 screw terminals LRD22

Overload relay – protection for motors and circuits

The TeSys LRD 22 thermal overload relay is a reliable device designed to protect motors and electrical circuits from the effects of overloads. Its function is to protect against damage resulting from excessive load, phase failure, prolonged starting, or rotor overload. This is a key element in ensuring the continuity of electrical installation operation and extending the service life of connected devices.

Construction and functionality

The LRD22 relay is characterized by its versatility and ease of integration with other automation elements. Screw terminals provide secure and durable wire connections, and direct mounting simplifies installation. The reset button allows manual resetting of the device after a trip caused by an overload, while the automatic reset function allows the circuit to restart after working conditions stabilize. Built-in auxiliary contacts (1 normally open and 1 normally closed) expand the possibilities of using the relay in control and signaling systems.

Key features and benefits

• Wide current setting range: 16…24 A – allows adaptation to various applications and loads.
• Trip class 10 A: ensures a quick response to overloads, minimizing the risk of damage to the protected circuit.
• Compatibility with TeSys Deca: perfectly integrates with TeSys Deca series contactors, creating an integrated control system.
• Multifunctionality: protection against overload, phase failure, prolonged starting and rotor overload – one device provides comprehensive protection.
• Built-in auxiliary contacts: facilitate integration with control and signaling systems without the need for additional elements.
• Manual or automatic reset option: flexibility in choosing the method of resetting the device depending on the application needs.
• Maximum operating voltage 690 V: allows use in a wide range of electrical installations with different rated voltages.
• Direct mounting: simplifies and speeds up the installation process.

The LRD22 relay is a solid solution for both professional installers and end-users looking for reliable protection for their electrical installations. Its versatility, functionality and ease of installation make it an ideal choice for a wide range of industrial and commercial applications.
