Schneider Electric LR9F5367 Thermal Overload Relay

Description:

The Schneider Electric LR9F5367 Thermal Overload Relay is used in motor control systems to provide electronic overload, phase loss, and phase imbalance protection for large three-phase motors and industrial drive applications. Commonly installed in motor control centers, conveyors, pumps, compressors, crushers, and heavy-duty manufacturing equipment utilizing TeSys F 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 LR9F5367 electronic overload relay is commonly used in manufacturing facilities, mining operations, water treatment plants, material handling systems, and process industries where high-power motors require precise overload and phase failure protection. Designed for use with Schneider Electric LC1F115 through LC1F185 contactors, the relay provides adjustable motor protection with Class 10 tripping characteristics for industrial motors ranging from approximately 37 to 45 kW at 400V.
