DESCRIPCIÓN DEL PRODUCTO
SCHNEIDER ELECTRIC LRD332C - Thermal Overload Relay
SCHNEIDER ELECTRIC LRD332C is a TeSys LRD series thermal overload relay engineered for robust motor protection in industrial control applications. This electromechanical device provides essential thermal overload and phase loss protection for AC motors, integrating directly with TeSys D contactors. It is designed to safeguard critical machinery, including pumps, fans, conveyors, and HVAC systems, by preventing motor damage due to sustained overcurrent conditions.
