SCHNEIDER ELECTRIC LRD3806 - Thermal Overload Relay
The SCHNEIDER ELECTRIC LRD3806 is a TeSys LRD series 3-pole thermal overload relay, specifically engineered for the thermal protection of AC motors. It provides Class 10A overcurrent and phase loss protection, integrating directly with TeSys D contactors for motor control circuits in industrial applications such as pumping, ventilation, and conveying systems. This device ensures operational continuity and prevents motor damage due to sustained overloads.
