Schneider Electric LR2D1301 NSNBC01 Thermal Overload Relay

Description:

The Telemecanique LR2D1301 thermal overload relay is a three-pole motor protection relay with an adjustable current range of 0.1–0.16 A and Class 10A tripping characteristics, designed to protect three-phase motors against overload and phase-failure conditions in industrial motor control systems. Commonly installed in motor control centers, precision machinery, conveyors, laboratory equipment, packaging systems, and industrial automation applications using TeSys D motor starters. Maintenance teams, OEMs, and system integrators use this thermal overload relay for equipment repair, replacement, retrofit, and new motor starter installations.

Applications:

The Telemecanique LR2D1301 thermal overload relay provides adjustable overload and phase-loss protection for low-current three-phase motors when used with compatible TeSys D contactors. It is widely installed in manufacturing facilities, machine tools, process automation systems, material handling equipment, and industrial control panels where reliable motor protection helps maximize equipment uptime and extend motor life.
