SCHNEIDER ELECTRIC LRD3365 - Thermal Overload Relay
The SCHNEIDER ELECTRIC LRD3365 is a TeSys LRD series thermal overload relay designed for the protection of AC motors against sustained overcurrents and phase failure conditions. This electromechanical device integrates directly with TeSys D contactors, providing a robust and compact solution for motor control circuits in industrial automation, material handling, and HVAC systems. It ensures operational reliability and equipment longevity by monitoring motor current and initiating a trip sequence upon detection of abnormal load conditions.
