SCHNEIDER ELECTRIC LRD-32 - Thermal Overload Relay
The SCHNEIDER ELECTRIC TeSys LRD-32 is a three-pole thermal overload relay engineered for the protection of AC motors against overload, phase failure, and prolonged starting times. This electromechanical device integrates bimetallic strips for precise current sensing and is designed for direct mounting beneath TeSys D contactors, providing robust and reliable motor circuit protection in industrial control applications. It is suitable for use in systems requiring compliance with IEC 60947-4-1 standards.
