Schneider Electric LR2-D3563 Thermal Overload Relay

Description:

The Telemecanique LR2-D3563 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 LR2-D3563 is commonly used in industrial automation systems, machine tools, HVAC equipment, and process control applications where large 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 provides phase unbalance protection and Class 20 tripping characteristics for motors up to 37 kW at 400 VAC.
