Schneider Electric LR9F5367 Thermal Overload Relay

The Schneider Electric TeSys LR9F5367 electronic thermal overload relay is a 3-pole motor protection device designed for heavy-duty industrial applications, offering electronic overload and phase-failure protection with an adjustable current range of 60–100 A and Class 10 tripping when used with TeSys F contactors. It provides protection for three-phase motors and is compatible with LC1F115, LC1F150, and LC1F185 contactors, with a rated voltage of up to 1000 VAC and an auxiliary contact set of 1 NO + 1 NC. The relay mounts directly to a contactor or on a plate via screw-clamp terminals, carries IP20 protection, and operates from -20°C to +70°C, making it suitable for installation in motor control centers, pumps, compressors, conveyors, process equipment, and heavy industrial machinery; common replacements include Schneider Electric LR9G115.
