Thermal overload protection Phase failure sensitivity Adjustable current setting Manual/Automatic reset 1NO+1NC auxiliary contacts Direct mounting with TeSys D contactors

The Schneider Electric LRD08 is a 3-pole thermal overload relay from the TeSys Deca series, engineered for the protection of electric motors against overcurrents and phase faults. It features an adjustable current setting range of 2.5-4A, a tripping class of 10A, and employs bimetallic elements for reliable thermal sensing. This relay supports manual or automatic reset and includes auxiliary contacts for fault signaling.

This overload relay is a critical component for motor protection in industrial environments, ensuring the longevity and operational integrity of equipment such as larger pumps, compressors, and machine tools. By detecting overloads and phase imbalances, it initiates a disconnect, preventing motor damage and minimizing costly downtime. It is designed for direct mounting onto Schneider Electric TeSys D contactors (LC1D09-D38).

Stanlo Automation provides the Schneider Electric LRD08 for your motor protection needs. As a veteran-owned surplus parts distributor, we are committed to delivering high-quality components and efficient service to keep your industrial operations running securely.
