Product Description
It is part of the TeSys D series and is intended for use with Schneider Electric's TeSys D contactors, specifically the LC1D18, LC1D25, and LC1D32 models. The relay features a current setting range of 16 to 24 amperes and is classified as Class 10A, meaning it trips within 10 seconds at 7.2 times the current setting, providing rapid protection for motors. The LRD22 offers a wide range of functions including manual or automatic reset, trip indication, and a test button. It also has a stop button for manual control. The relay is designed to operate in harsh industrial environments, with a degree of protection of IP20 for the terminals and a robust construction that withstands vibration and temperature variations. Its compact design allows for easy mounting directly onto the contactor or separately on a DIN rail using an adapter. This thermal overload relay is compliant with major international standards including IEC 60947-4-1, UL 508, and CSA C22.2. It is suitable for a variety of applications such as motor control centers, conveyor systems, pumps, fans, and compressors. The LRD22 is a reliable and cost-effective solution for motor protection, ensuring long service life and reduced downtime. The Schneider LRD22 is a thermal overload relay designed for the protection of AC motors against overload, phase failure, and phase unbalance.

Technical Specifications
Version & Model Difference
The LRD22 is part of the LRD series of thermal overload relays from Schneider Electric. The series includes models with different current ranges, such as LRD01 (0.1-0.16 A), LRD02 (0.16-0.25 A), and so on, up to LRD35 (30-40 A). The LRD22 specifically covers the 16-24 A range. Compared to older LR2 series relays, the LRD series offers improved accuracy, a more compact design, and better compatibility with TeSys D contactors. The LRD22 is a current version and is widely used in modern motor control applications.
