SCHNEIDER ELECTRIC LRD380 - Thermal Overload Relay
The SCHNEIDER ELECTRIC LRD380 is a TeSys LRD series thermal overload relay engineered for robust motor protection in industrial control systems. This device provides essential safeguarding against overloads, phase failure, and prolonged starting conditions for three-phase AC motors, integrating directly with TeSys D contactors. It is critical for maintaining operational integrity and extending the lifespan of machinery in applications such as pumping, ventilation, conveying, and general machine control.
