SCHNEIDER ELECTRIC LRD340C - Thermal Overload Relay
The SCHNEIDER ELECTRIC LRD340C is a 3-pole TeSys LRD thermal overload relay engineered for the electromechanical protection of AC motors. It safeguards against overload conditions, phase failure, and extended starting times, integrating directly with TeSys D contactors. This device is critical for maintaining operational integrity in industrial motor control circuits, including those found in pumping stations, HVAC systems, and material handling equipment.
