Schneider Electric LRD07 Thermal Overload Relay

Description:

The Telemecanique LRD07 Thermal Overload Relay is an adjustable motor protection relay used in industrial motor control systems to provide overload protection and phase failure detection for electric motors. Commonly installed in motor starters, conveyors, pumps, compressors, and manufacturing equipment requiring reliable thermal protection. Maintenance teams and system integrators use this relay for replacement, retrofit, and expansion of motor control systems to improve equipment safety and reduce unplanned downtime.

Applications:

The Telemecanique LRD07 is commonly used in industrial automation systems, machine tools, HVAC equipment, and process control applications where three-phase motors require adjustable overload protection. Its compatibility with TeSys D contactors makes it suitable for motor control centers, electrical panels, and OEM machinery operating in demanding industrial environments. The relay features phase-loss sensitivity and can be mounted directly to LC1D09 through LC1D38 contactors or separately on DIN rail installations.
