LRD12C Thermal Overload Relay 5.5-8 Amp.

Description:

The Schneider Electric LRD12C Thermal Overload Relay is used in motor control systems to provide adjustable overload and phase loss protection for three-phase motors and industrial drive applications. Commonly installed in motor starters, conveyors, pumps, compressors, and manufacturing equipment utilizing TeSys D contactors. Maintenance teams, OEM machine builders, and system integrators use this relay for motor protection upgrades, replacement of failed overload devices, and industrial control panel retrofits.

Applications:

The LRD12C thermal overload relay is commonly used in manufacturing facilities, HVAC equipment, water treatment plants, material handling systems, and process industries where motors require reliable protection against overload conditions and phase failure. Designed for use with Schneider Electric LC1D09 through LC1D38 contactors, the relay provides Class 10A tripping characteristics for motors requiring 5.5 to 8 amp protection in continuous-duty industrial applications.
