SCHNEIDER ELECTRIC LRD326 - Thermal Overload Relay
The SCHNEIDER ELECTRIC LRD326 is a TeSys LRD series thermal overload relay engineered for robust motor protection in industrial control systems. It provides reliable protection against overloads, phase failure, and prolonged starting times for AC motors, integrating seamlessly with TeSys D contactors. This device is critical for maintaining operational continuity and preventing damage to three-phase induction motors in applications such as pumping, ventilation, and material handling.
